Subject: OMAP: DSS2: Add picodlp panel driver

PicoDLP is a micro projector from TI.

DLP used in OMAP4 is dpp2600 (DLP Pico Projector) The DLP requires
commands to be sent over i2c for configurations. To know more about
dpp2600 commands please visit:
https://focus.ti.com/myti/docs/extranet.tsp?sectionId=403

The picodlp module consists of a dss driver and an i2c_client.

To know more please visit:

Based on original design from Mythri P K <mythripk@ti.com>

- If omapdss_dpi_display_enable() failed, the its error value was not
  returned
- If picodlp_i2c_init() failed, dssdev->state was erroneously set to

Subject: OMAP: DSS2: check for manager when enabling display

None of the DSS interface drivers check if an overlay manager is
connected to the display when the display is being enabled. This leads
to null pointer crash if the display has no manager.

This patch checks for the manager and returns an error if it is null.

Subject: OMAP: DSS2: Don't allow moving managers away from enabled displays

If a manager is moved while attached to an enabled display, the DSS
system will be left in an inconsistent state. This will eventually cause
a kernel oops when the enabled display is disabled.

Fix this by not allowing the user to move a manager away from an enabled
display.

Subject: OMAP: DSS2: DISPC: Prepare dispc_dump_regs() for shortening

Prepare dispc_dump_regs() to iterate over manager and overlay id's. Doing this
requires modifications of the macro "DUMPREG" which currently needs us to specify
the manager/overlay name to get the correct result. For example, in order to
print the register DISPC_TIMING_H(OMAP_DSS_CHANNEL_LCD), we can't iterate over
a varaible i and get the desired result through DUMPREG(DISPC_TIMING_H(i)).

Split the registers into 3 sections, the first with no arguments(common
registers), the second with one argument(manager/overlay id), and the third with
two arguments(overlay id and coefficient index), redefine DUMPREG macros for
each of these.

Subject: OMAP: DSS2: Use a macro to declare size of the fifo_size array in
 dispc.c

The array size of fifo_size array in the global dispc struct is currently
hardcoded to 3. Replace this with the MAX_DSS_OVERLAYS macro in dss_features.h,
use dss_features function to get the number of overlays instead of the
ARRAY_SIZE macro in dispc_read_plane_fifo_sizes().

Subject: OMAP: DSS2: remove unneeded fck enable/disables

Now that the HWMOD fmwk handles the fcks of DSS modules properly, the
DSS driver no longer needs to explicitely enable/disable the fck.

This patch removes the enables/disables of fck from dispc, dsi and dss.
The clk_get(fck) is still needed there, as the modules need to know the
frequency of the clock.

For hdmi and venc this patch also removes the clk_get(fck), as they
don't need the clock at all.

Subject: OMAP: DSS2: Change DSI device naming

Currently, there are 2 differently named platform devices generated for
the 2 DSS DSI modules. In order to use the same driver, the dsi devices
should be 2 instances of the same platform device.

Change the platform device names from "omapdss_dsi1" and "omapdss_dsi2"
to omapdss_dsi", and set the device indices to 0 and 1.

Subject: OMAP4: TWL: Add common omapdss supplies

OMAP DSS normally gets power from VCXIO on OMAP4. Add configuration for
this into twl-common.c

Mark VCXIO as always_on, as VCXIO is used by multiple components,
including the MPU, and turning it off when DSS doesn't need it would
lead the device to halt.

Subject: OMAP: DSS2: Implement dsi_mux_pads for OMAP4

Implement dsi_mux_pads for OMAP4. On enable the function enables the DSI
pins and disables pull down. On disable the function disables the pins
and enables pull down.

It is unclear from the TRM whether the pull down is active if the pins
are disabled, so this implementation may leave the pins floating when
the DSI device is disabled.

Currently omapfb wants that all the display devices have a driver,
otherwise omapfb refuses to start. There's no real requirement to act
like that, and this patch will make omapfb give a warning and skip that
device.

Subject: OMAP: DSS2: Handle manager change in apply

Currently when changing the manager of an overlay, set_manager() directly
calls dispc to set the overlay's destination.

Change this to be more in line with other overlay configurations, and
this will also remove the need to have dispc clocks enabled when calling
set_manager().

A new field is added to overlay struct, "manager_changed". This is
similar to "display_changed" field in manager struct, and is used to
inform apply that the manager has changed and thus write to the
registers is needed.

Subject: OMAP: DSS2: Remove support for non-DISPC overlays

Remove support for non-DISPC overlays and overlay managers.

The support to possibly have non-DISPC overlays and managers was made to
make it possible to use CPU and/or sDMA to update RFBI or DSI command
mode displays. It is ok to remove the support, because:

- No one has used the feature.
- Display update without DISPC is very slow, so it is debatable if the
  update would even be usable.
- Removal cleans up code.
- If such a feature is needed later, it is better implemented outside
  omapdss driver.

Subject: OMAP: DSS2: Add GLOBAL_ALPHA & PRE_MULT_ALPHA to ovl caps

Add OMAP_DSS_OVL_CAP_GLOBAL_ALPHA and OMAP_DSS_OVL_CAP_PRE_MULT_ALPHA to
overlay capabilities. Use these instead of FEAT_GLOBAL_ALPHA,
FEAT_GLOBAL_ALPHA_VID1 and FEAT_PRE_MULT_ALPHA in code.

Remove FEAT_GLOBAL_ALPHA_VID1 and FEAT_PRE_MULT_ALPHA which are no
longer used. FEAT_GLOBAL_ALPHA is still used to decide if the HW has
global alpha register.

Subject: OMAP: DSS2: DISPC: rename overlay related funcs

Rename dispc's overlay related functions as follows:

- Remove prepending underscores, which were originally used to inform
  that the clocks needs to be enabled. This meaning is no longer valid.
- Prepend the functions with dispc_ovl_*
- Remove "plane" from the name, e.g. dispc_set_plane_ba0 ->
  dispc_ovl_set_ba0

The idea is to group overlay related functions so that it can be deduced
from the function name that it writes to overlay spesific registers.

All dispc_ovl_* functions have enum omap_plane as the first parameter.

From 26d9dd0dbe09e8a6d1f8c8ed90cd29b049bfa6ee Mon Sep 17 00:00:00 2001

Subject: OMAP: DSS2: DISPC: rename manager related funcs

Rename dispc's manager related functions as follows:

- Remove prepending underscores, which were originally used to inform
  that the clocks needs to be enabled. This meaning is no longer valid.
- Prepend the functions with dispc_mgr_*
- Remove "channel" from the name, e.g. dispc_enable_channel ->
  dispc_mgr_enable

The idea is to group manager related functions so that it can be deduced
from the function name that it writes to manager spesific registers.

All dispc_mgr_* functions have enum omap_channel as the first parameter.

Subject: OMAP: DSS2: DSI: Represent L4 and VP as sources of VC instead of
 modes

The enum type dsi_vc_mode is a bit misleading as L4 slave port and video port
are sources to VC rather than the mode of operation. Rename then enum type and
its members. Merge dsi_vc_config_vp() and dsi_vc_config_l4() into a single
function called dsi_vc_config_source() which takes dsi_vc_source enum as an
extra argument.

Subject: OMAP: DSS2: DSI: Introduce generic write functions

Intoduce enum "dss_dsi_content_type" to differentiate between DCS and generic
content types.

Introduce short and long packet write functions which use generic
Processor-to-Peripheral transaction types. These are needed by some devices
which may not support corresponding DCS commands. Create common write functions
which allow code reuse between DCS and generic write functions.

Subject: OMAP: DSS2: DSI: Remove functions dsi_vc_dcs_read_1() and
 dsi_vc_dcs_read_2()

Remove functions dsi_vc_dcs_read_1() and dsi_vc_dcs_read_2(), these are used
when the panel is expected to return 1 and 2 bytes respecitvely. This was manily
used for debugging purposes. These functions should be implemented in the panel
driver if needed.

- dsi_vc_dcs_read_rx_fifo(): This parses the DSI RX fifo of the given virtual
channel, identifies the type of data received, and fills a buffer with the data
provided by the panel.

Subject: OMAP: DSS2: DSI: Introduce generic read functions

Introduce read functions which use generic Processor-to-Peripheral
transaction types. These are needed by some devices which may not support
corresponding DCS commands.

Add function dsi_vc_generic_send_read_request() which can send
a short packet with 0, 1 or 2 bytes of request data and the corresponding
generic data type.

Rename function dsi_vc_dcs_read_rx_fifo() to dsi_vc_read_rx_fifo() and modify
it to take the enum "dss_dsi_content_type" as an argument to use either DCS
or GENERIC Peripheral-to-Processor transaction types while parsing data read
from the device.

Subject: OMAP: DSS2: Clean up stallmode and io pad mode selection

Split the function dispc_set_parallel_interface_mode() into 2 separate
functions called dispc_mgr_set_io_pad_mode() and dispc_mgr_enable_stallmode().
The current function tries to set 2 different modes(io pad mode and stall mode)
based on a parameter omap_parallel_interface_mode which loosely corresponds to
the panel interface type.

This isn't correct because a) these 2 modes are independent to some extent,
b) we are currently configuring gpout0/gpout1 for DSI panels which is
unnecessary, c) a DSI Video mode panel won't get configured correctly.

Splitting the functions allows the interface driver to set these modes
independently and hence allow more flexibility.

From a3b3cc2b883aac18a3388a405db809a99d66e3cf Mon Sep 17 00:00:00 2001

Subject: OMAP: DSS2: Create an enum for DSI pixel formats

Currently, DSI pixel info is only represented by the pixel size in bits using
the pixel_size parameter in omap_dss_device struct's ctrl member.

This is not sufficient information for DSI video mode usage, as two of the
supported formats(RGB666 loosely packed, and RGB888) have the same pixel
container size, but different data_type values for the video mode packet header.

Create enum "omap_dss_dsi_pixel_format" which describes the pixel data format
the panel is configured for. Create helper function dsi_get_pixel_size() which
returns the pixel size of the given pixel format.

Modify functions omapdss_default_get_recommended_bpp() and dss_use_replication()
to use dsi_get_pixel_size().

Subject: OMAP: DSS2: DSI: Send zero length packet in dsi_vc_send_null()

dsi_vc_send_null() currently sends a long packet with data type
MIPI_DSI_NULL_PACKET and packet length 4. Modify it to send a zero
length long packet. This leads to sending only the long packet header
and no payload packets and hence the transfer completes faster.

The function can be modified later if there is a need to send null
packets of a non-zero length.

Subject: OMAP: DSS2: DSI Video mode support

Add initial support for DSI video mode panels:
- Add a new structure omap_dss_dsi_videomode_data in the member "panel" in
  omap_dss_device struct. This allows panel driver to configure dsi video_mode
  specific parameters.
- Configure basic DSI video mode timing parameters: HBP, HFP, HSA, VBP, VFP, VSA,
  TL and VACT.
- Configure DSI protocol engine registers for video_mode support.
- Introduce functions dsi_video_mode_enable() and dsi_video_mode_disable() which
  enable/disable video mode for a given virtual channel and a given pixel format
  type.

Things left for later
- Add functions to check for errors in video mode timings provided by panel.
- Configure timing registers required  for command mode interleaving.

Subject: OMAP4: DSS2: HDMI: HDMI clean up to pass base_address

As the base_address of the HDMI might differ across SoC's, offset of the HDMI
logical blocks(PHY, PLL and Core) and base address procured from the platform
data are passed dynamically to the functions that modify HDMI IP registers.

Subject: OMAP4: DSS2: HDMI: Move pll and video configuration

As the pll and the video configuration info are part of the ip_data, pll
and video structures are moved to the ip_data structure. Also the pll and
video configuration functions are modified accordingly to take care of the
structure movement.

Subject: OMAP4: DSS2: HDMI: Use specific HDMI timings structure

As hdmi has few additional parameters such as vsync and hsync
polarity which is missing in DSS timing structure, define HDMI timings
structure for hdmi to use instead of OMAP DSS timing structure.

Subject: OMAP4: DSS2: HDMI: Split the current HDMI driver to move

Split the current HDMI driver to move the HDMI IP dependent ( PLL/PHY/Core
configuration code) to a new IP file (ti_hdmi_4xxx_ip.c.
This is to separate IP dependent OMAP agnostic code from OMAP specific DSS
dependent code.

Subject: OMAP4: DSS2: HDMI: Function pointer approach to call

HDMI IP fundamentally has replaceable core PHY and PLL blocks.
These blocks might vary across OMAP's but the end functionality such as to
enable or disable PLL, PHY, function to read EDID would remain the same.

Thus to make the current hdmi DSS driver compatible with different OMAP's having
different IP blocks( A combination of different core, PHY, PLL blocks), function
pointer approach is introduced.

With function pointer, relevant IP dependent functions are mapped to the generic
functions used by DSS during the initialization based on the OMAP compiled.
Thus making hdmi DSS driver IP agnostic.

From 9eaaf2076dac213c034c69051dd7a625cd41f56e Mon Sep 17 00:00:00 2001
From: Tomi Valkeinen <tomi.valkeinen@ti.com>

Subject: OMAP: DSS2: DISPC: Fix minimum PCD value

The current driver had a hardcoded minimum value of 2 for pixel clock
divisor (PCD). This doesn't seem to be right.

OMAP4 TRM says that PCD can be 1 when not downscaling, and inverted
pixel clock (IPC) is off.

OMAP3 TRM says the same, but also in the register descriptions that PCD
value 1 is invalid.

OMAP2 TRM says PCD 2 is the minimum.

OMAP2 is still untested, but for both OMAP3 and OMAP4 PCD of 1 seems to
work fine.

This patch adds a new DSS feature, FEAT_PARAM_DSS_PCD, which is used to
find the minimum and maximum PCD. The minimum is set to 2 for OMAP2, and
1 for OMAP3/4.

Subject: OMAP: DSS2: HDMI: change regn definition

regn divider is currently programmed to the registers without change,
but when calculating clock frequencies it is used as regn+1.

To make this similar to how DSI handles the dividers this patch changes
the regn value to be used as such for calculations, but the value
programmed to registers is regn-1.

This simplifies the clock frequency calculations, makes it similar to
DSI, and also allows us to use regn value 0 as undefined.

Subject: OMAP: DSS2: HDMI: improve hdmi output enable

Enabling HDMI output often causes sync lost errors, and almost always
causes timeout errors being printed from dispc_mgr_enable_digit_out().

The sync lost problem seems to go lessen greatly if we first enable the
HDMI output, and only then enable the DISPC output. However, as this is
only based on observations, the fix may not be perfect as the problem
may lie somewhere else. Nevertheless, HDMI works better with this patch.

This will also fix the dispc's dispc_mgr_enable_digit_out(), as the code
waits for two VSYNCs after enabling the output. If the HDMI output is
disabled (as it was previously), there are no VSYNCs and
dispc_mgr_enable_digit_out() will print timeout errors.

Subject: OMAP: DSS2: HDMI: make set_timing saner

Currently the set_timings code for hdmi is quite strange. The display is
disabled in hdmi_omap4_panel.c before setting timings, and enabled in
hdmi.c after setting the timings. Furthermore, the timings were not
permanent, and disabling and enabling the display would lose them.

This patch makes the set_timings handling a bit better.

Subject: OMAP: DSS2: HDMI: clean up edid reading & fix checksum

Clean up reading of EDID by passing direct address to the block being
read, instead of start address of the whole EDID memory area. Rewrite
the loop which reads the EDID.

This also fixes the checksum calculation, which used to calculate the
checksum only for the first block.

Subject: OMAP: DSS2: HDMI: remove error prints in check_timings

check_timings() is supposed to be used to verify if timings are ok or
not. Currently the HDMI driver prints error messages if the timings are
not ok. This is not right, as it is no error to give invalid timings to
check_timings().

Remove the error prints.

Subject: OMAP: DSS2: HDMI: implement detect()

Implement detect() by checking the hot plug detect status.

The implementation is not very good, as it always turns on the HDMI
output to get the detection working. HDMI driver needs improvements so
that we could enable only core parts of it.

Subject: OMAP: DSS2: add panel-dvi driver

We have currently panel-generic-dpi driver, which is a combined driver
for dummy panels and also for DVI output.

The aim is to split the panel-generic-dpi into two, one for fixed size
dummy panels connected via DPI, and the other (this) for variable
resolution output which supports DDC channel (in practice a DVI framer
chip connected to DPI output).

From 1d7a8654e88885137ade1769c574467775fde27b Mon Sep 17 00:00:00 2001
From: Tomi Valkeinen <tomi.valkeinen@ti.com>
Date: Thu, 1 Sep 2011 10:13:04 +0300
Subject: OMAP: use dvi panel driver instead of generic-dpi

Multiple OMAP3/4 boards have a DVI framer output. This patch makes the
boards use the new panel-dvi driver, instead of the panel-generic-dpi
driver.

Separate drivers for fixed size panels and DVI framer gives us cleaner
driver code.

Subject: OMAP: stalker: Remove LCD device from board file

OMAP3 Stalker board has definitions for LCD, but uses the generic driver
without any information what kind of LCD it has. The board should use a
particular panel type from panel-generic-dpi driver, not the generic
one.

As I haven't gotten response the signer-off of stalker board about the
issue, this patch removes the LCD support from the board file. This will
allow us to clean up the panel-generic-dpi driver and make it support
only fixed size panels.

at initialization time.

Hot-plug is not yet supported, so the timings selected at init time will
stay even if the monitor would be changed.

Subject: OMAPDSS: DISPC: Reduce the number of arguments in dispc_ovl_setup()

dispc_ovl_setup() currently takes a large number of overlay arguments, most of
these are members of the overlay_info struct. Replace these arguments by
passing a overlay_info pointer instead.

In configure_overlay(), we create an overlay_info struct called new_oi, this is
a copy of the overlay cache's overlay_info member. Update the new_oi parameters
which could have been possibly changed in configure_overlay(). Pass its pointer
pointer to dispc_ovl_setup().

Subject: OMAPDSS: DISPC: Pass overlay params as arguments to dispc_ovl_setup()

dispc_ovl_enable_replication() and dispc_ovl_set_fifo_threshold() are currently
called in configure_overlay(). These are the only functions which cause DISPC
register writes of overlay parameters outside of dispc_ovl_setup().

Move these to dispc_ovl_setup() and pass replication, fifo_low and fifo_high
thresholds as arguments to dispc_ovl_setup() in order to be aligned with other
overlay parameters. No functional changes are made.

Subject: OMAPDSS: DISPC: Get correct pixel clock for TV manager

dispc_mgr_pclk_rate() is used to calculate minimum required functional clock for
scaling in calc_fclk() and calc_fclk_five_taps(). This function returns the
correct pixel clock for LCD and LCD2 managers, but not for TV manager. Extend
this function so that it gets the correct pixel clock for TV manager.

This also prevents the crash we get when we try to scale overlays connected to
TV manager. The current code leads to a BUG() being executed if we call
dispc_mgr_pclk_rate() for the TV manager.

Subject: OMAPDSS: DISPC: Remove hardcoded use of PPL in five tap clock
 calculation

The function calc_fclk_five_taps() uses a fixed value of pixels per line which
is used in calculations to get the minimum fclk needed for scaling with five
taps to work.

Remove this by providing the width of the panel connected to the manager.

Subject: OMAPDSS: Taal: remove external backlight support

Taal panel driver supports two kinds of backlight control: 1) using DSI
commands sent to the panel to control the backlight, 2) calling function
pointers going to the board file to control the backlight.

The second option is a bit hacky, and will no longer be needed when the
PWM driver supports the backlight features. After that we can use the
standard PWM backlight driver.

This patch removes the second backlight control mechanism, and adds a
boolean field, use_dsi_backlight, to nokia_dsi_panel_data which the
board file can use to inform whether the panel driver should use DSI
commands to control the backlight.

Subject: OMAPDSS: Add N800 panel driver

This is a driver for N800's display, ported from the old omapfb. This is
a slightly lighter version of the driver as not all features of the old
driver can be ported without big changes to DSS2, and also because some
of the HW features used in the old driver are unclear (e.g. the power
management part).

That said, the new driver works fine for basic use.

Architecturally the driver is not as neat as it could be. N800's display
HW consists of a display buffer chip and a panel, and ideally they would
be represented by separate, independent drivers. This is not currently
possible, and this driver contains both buffer chip and panel driver.

Subject: OMAPDSS: remove vaddr from overlay info

overlay_info struct, used to configure overlays, currently includes both
physical and virtual addresses for the pixels. The vaddr was added to
support more exotic configurations where CPU would be used to update a
display, but it is not currently used and there has been no interest in
the feature. Using CPU to update a screen is also less interesting now
that OMAP4 has two LCD outputs.

This patch removes the vaddr field, and modifies the users of omapdss
accordingly. This makes the use of omapdss a bit simpler, as the user
doesn't need to think if it needs to give the vaddr.

Subject: OMAP4: 4430SDP: Add panel support to board file

4430SDP has two Taal DSI panels, connected to DSI 1 and DSI 2 modules.
The panels use a common PWM backlight, which will be implemented later
when the PWM driver has been improved to support the backlight.

Until the PWM driver has been improved, the following hack added to
arch/arm/mach-omap2/board-4430sdp.c can be used to set the backlight to
max:

static int omap_4430sdp_hack_backlight(void)
{
       twl_i2c_write_u8(TWL_MODULE_PWM, 0x7f, LED_PWM2OFF);
       twl_i2c_write_u8(TWL_MODULE_PWM, 0x7f, LED_PWM2ON);
       twl_i2c_write_u8(TWL6030_MODULE_ID1, 0x30, TWL6030_TOGGLE3);
       return 0;
}

Subject: OMAP4: 4430SDP: Add picodlp support to board file

An on-board projector named picodlp is available for OMAP4430 SDP.

Entry for this picodlp as a panel is being added in dss_devices array to
the board file.  It needs 4 GPIO pins for interfacing with host
processor and these are defined and two of them are configured in board
file.  Two GPIOs power_on and display_select are configured here.
picodlp also needs an i2c client over i2c controller-2 at address 0x1b.

Subject: OMAP: RX51: Remove unused old omapfb stuff

RX51 uses the new DSS2 display driver, but the board file still
contained some code for the old omapfb driver. The old code can be
removed.

Subject: OMAPDSS/OMAP_VOUT: Fix incorrect OMAP3-alpha compatibility setting

On OMAP3, in order to enable alpha blending for LCD and TV managers, we needed
to set LCDALPHABLENDERENABLE/TVALPHABLENDERENABLE bits in DISPC_CONFIG. On
OMAP4, alpha blending is always enabled by default, if the above bits are set,
we switch to an OMAP3 compatibility mode where the zorder values in the pipeline
attribute registers are ignored and a fixed priority is configured.

Rename the manager_info member "alpha_enabled" to "partial_alpha_enabled" for
more clarity. Introduce two dss_features FEAT_ALPHA_FIXED_ZORDER and
FEAT_ALPHA_FREE_ZORDER which represent OMAP3-alpha compatibility mode and OMAP4
alpha mode respectively. Introduce an overlay cap for ZORDER. The DSS2 user is
expected to check for the ZORDER cap, if an overlay doesn't have this cap, the
user is expected to set the parameter partial_alpha_enabled. If the overlay has
ZORDER cap, the DSS2 user can assume that alpha blending is already enabled.

Don't support OMAP3 compatibility mode for now. Trying to read/write to
alpha_blending_enabled sysfs attribute issues a warning for OMAP4 and does not
set the LCDALPHABLENDERENABLE/TVALPHABLENDERENABLE bits.

Change alpha_enabled to partial_alpha_enabled in the omap_vout driver. Use
overlay cap "OMAP_DSS_OVL_CAP_GLOBAL_ALPHA" to check if overlay supports alpha
blending or not. Replace this with checks for VIDEO1 pipeline.

From: Archit Taneja <archit@ti.com>
Date: Tue, 13 Sep 2011 18:20:33 +0530
Subject: OMAPDSS: DISPC: VIDEO3 pipeline support

Add support for VIDEO3 pipeline on OMAP4:
- Add VIDEO3 pipeline information in dss_features and omapdss.h
- Add VIDEO3 pipeline register coefficients in dispc.h
- Create a new overlay structure corresponding to VIDEO3.
- Make changes in dispc.c for VIDEO3

Subject: OMAPDSS: DISPC: zorder support for DSS overlays

Add zorder support on OMAP4, this feature allows deciding the visibility order
of the overlays based on the zorder value provided as an overlay info parameter
or a sysfs attribute of the overlay object.

Use the overlay cap OMAP_DSS_OVL_CAP_ZORDER to determine whether zorder is
supported for the overlay or not. Use dss feature FEAT_ALPHA_FREE_ZORDER
if the caps are not available.

Ensure that all overlays that are enabled and connected to the same manager
have different zorders. Swapping zorders of 2 enabled overlays currently
requires disabling one of the overlays.
