This patch makes use of the hdmi_power_[on|off]_core() functions added
in the previous patch. The functions are used when reading EDID or
detecting if a monitor is connected.

There's currently just one power-on function for HDMI, which enables the
IP and the video output. When reading EDID or detecting if a monitor is
connected, we don't need the video output.
Enabling the video output for these operations is not a big problem in
itself, but the quick enable/disable cycles caused by the operations
seem to cause sync lost errors from time to time. Also, this makes it
possible to read the EDID before the full video path has been set up.
This patch splits the hdmi_power_on into two parts, hdmi_power_on_core
and hdmi_power_on_full. The "full" version does what hdmi_power_on does
currently, and hdmi_power_on_core only enables the core IP. Similar
changes are made for power_off.
Note that these don't allow the HDMI IP to be first enabled, and later
enable the video output, but the HDMI IP will first need to be powered
off before calling the full version. So this is rather limited
implementation, but it fills the needs for reading EDID.

DISPC irqs need to be handled from the compat layer and also in the
future by the omapdrm. To make this possible, this patchs adds a set of
helper functions, so that the irqs can be managed without direct
register reads/writes.
The following functions are added, and all the current direct reg
reads/writes are changed to use these.
u32 dispc_read_irqstatus(void);
void dispc_clear_irqstatus(u32 mask);
u32 dispc_read_irqenable(void);
void dispc_write_irqenable(u32 mask);

We need a low level manager-enable function for omapdrm. We have that
function as dispc internal func, _enable_mgr_out().
This patch exposes that function, and renames it to dispc_mgr_enable().

The current dispc_mgr_enable/disable function are blocking, and do a bit
too much for omapdrm. We'll expose new enable & disable functions that
will just set the bits in the registers in the following patches.
This patch renames the current functions to *_sync, to make it clear
that they are blocking, and also to free up the dispc_mgr_enable/disable
names for these new functions.

Use dss_feat_get_num_ovls() in dispc.c instead of
omap_dss_get_num_overlays() to remove the dependency to overlay.c. Note
that we still have uses of omap_dss_get_num_overlays() in dispc.c, but
these will be moved out in the future patches.

Currently omapdss driver sets up the initial connections between
overlays, overlay manager and a panel, based on default display
parameter coming from the board file or via module parameters.
This is unnecessary, as it's the higher level component that should
decide what display to use and how. This patch removes the code from
omapdss, and implements similar code to omapfb.
The def_disp module parameter and the default display platform_data
parameter are kept in omapdss, but omapdss doesn't do anything with
them. It will just return the default display name with
dss_get_default_display_name() call, which omapfb uses. This is done to
keep the backward compatibility.

Export dss_get_def_display_name() with the name of

The output drivers get the omapdss hw version from the platform data for
their respective output device. This doesn't work with DT, as there's no
platform data for them.
Add a new function, omapdss_get_version(), which returns the dss version
from the core device, which will have platform data on DT also. The
function is exported so that users of omapdss can also use it.

The panel drivers contain enable, disable, suspend and resume calls.
The suspend and resume are effectively identical to disable and enable.
This patch removes panel suspend and enable code from omapdss and the
panel drivers, and replaces their use with enable and disable.

We currently have a single function to enable and disable the manager
output for LCD and DIGIT. The functions are a bit complex, as handling
both enable and disable require some extra steps to ensure that the
output is enabled or disabled properly without errors before exiting the
function.
The code can be made simpler to understand by splitting the functions
into separate enable and disable functions. We'll also clean up the
comments and some parameter names at the same time.

Dispc has a bunch of functions used to configure output related
parameters:
- dispc_mgr_set_io_pad_mode
- dispc_mgr_enable_stallmode
- dispc_mgr_enable_fifohandcheck
- dispc_mgr_set_clock_div
- dispc_mgr_set_tft_data_lines
- dispc_lcd_enable_signal_polarity
- dispc_mgr_set_lcd_type_tft
These are all called together, and the configuration values are taken
from struct dss_lcd_mgr_config.
Instead of exposing those individual dispc functions, create a new one,
dispc_mgr_set_lcd_config(), which is used to configure the above
parameters from values in struct dss_lcd_mgr_config.

When we enable an output we don't check if we need to register the vsync
isr. This causes us to miss vsync interrupts until somebody changes the
configuration of an overlay or an overlay manager.

If dsi_get_dsidev_from_id() is called with a DSI module id that does not
exist on the board, the function will crash as omap_dss_get_output()
will return NULL.
This happens on omap3 boards when dumping DSI clocks, as the dumping
code will try to get the dsidev for DSI modules 0 and 1, but omap3 only
has DSI module 0.
Also clean up the id -> output mapping, so that if the function is
called with invalid module ID it will return NULL.

This patch converts vrfb library into a platform device, in an effort to
remove omap dependencies.
The platform device is registered in arch/arm/plat-omap/fb.c and
assigned resources depending on whether running on omap2 or omap3.

configuration registers and the vrfb virtual rotation areas.

Add new enum, omapdss_version, that is used to tell which DSS hardware
version the SoC has. This enum is initialized during platform init, and
passed in the platform data to omapdss driver.
Note that the versions are not "continuous", that is, you cannot check
if the version is less or greater than something, but you need to check
for exact version match. In other words, this is invalid:
/* test if DSS is 3630 or earlier */
if (ver <= OMAPDSS_VER_OMAP3630)

The hostprogs need access to the CONFIG_* symbols found in
include/generated/autoconf.h. But commit abbf1590de22 ("UAPI: Partition
the header include path sets and add uapi/ header directories") replaced
$(LINUXINCLUDE) with $(USERINCLUDE) which doesn't contain the necessary
include paths.
This has the undesirable effect of breaking the EFI boot stub because
the #ifdef CONFIG_EFI_STUB code in arch/x86/boot/tools/build.c is
never compiled.
It should also be noted that because $(USERINCLUDE) isn't exported by
the top-level Makefile it's actually empty in arch/x86/boot/Makefile.

Pull UAPI disintegration for include/linux/{,byteorder/}*.h from David Howells:
"The patches contained herein do the following:
(1) Remove kernel-only stuff in linux/ppp-comp.h from the UAPI. I checked
this with Paul Mackerras before I created the patch and he suggested some
extra bits to unexport.
(2) Remove linux/blk_types.h entirely from the UAPI as none of it is userspace
applicable, and remove from the UAPI that part of linux/fs.h that was the
reason for linux/blk_types.h being exported in the first place. I
discussed this with Jens Axboe before creating the patch.
(3) The big patch of the series to disintegrate include/linux/*.h as a unit.
This could be split up, though there would be collisions in moving stuff
between the two Kbuild files when the parts are merged as that file is
sorted alphabetically rather than being grouped by subsystem.
Of this set of headers, 17 files have changed in the UAPI exported region
since the 4th and only 8 since the 9th so there isn't much change in this
area - as one might expect.
It should be pretty obvious and straightforward if it does come to fixing
up: stuff in __KERNEL__ guards stays where it is and stuff outside moves
to the same file in the include/uapi/linux/ directory.
If a new file appears then things get a bit more complicated as the
"headers +=" line has to move to include/uapi/linux/Kbuild. Only one new
file has appeared since the 9th and I judge this type of event relatively
unlikely.
