Update SRAM start & size for am33xx SoC's.
Note: cpu_is_34xx() is true for am33xx also. Doing
cpu_is_am33xx() check after cpu_is_34xx() will not
achieve what we want due to the above reason.
Hence cpu_is_am33xx() is done before cpu_is_34xx()

Since omap_dm_timer_write_reg/__omap_dm_timer_write is now modified
to use timer->func_base OCP_CFG should not use this wrapper anymore.
Instead use __raw_writel() directly and use timer->io_base instead
to write to OCP_CFG.
The timer->sys_stat is valid only if timer->revision is 1. In the
context restore function make this correction.
Save the contexts and loss count when timer is stopped.
Also, disable the clock. Else, clock usecount would become imbalanced.

OMAP_DEVICE_NO_IDLE_ON_SUSPEND is set
During system suspend, when OMAP_DEVICE_NO_IDLE_ON_SUSPEND is set on
an omap_device, call the corresponding driver's ->suspend() and
->suspend_noirq() callbacks (if present). Similarly, during resume,
the driver's ->resume() and ->resume_noirq() callbacks must both be
called, if present. (The previous code only called ->suspend_noirq()
and ->resume_noirq().)
If all of these callbacks aren't called, some important driver
suspend/resume code may not get executed.
In current mainline, the bug fixed by this patch is only a problem
under the following conditions:
- the kernel is running on an OMAP4
- an OMAP UART is used as a console
- the kernel command line parameter 'no_console_suspend' is specified
- and the system enters suspend ("echo mem > /sys/power/state").
Under this combined circumstance, the system cannot be awakened via
the serial port after commit be4b0281956c5cae4f63f31f11d07625a6988766c
("tty: serial: OMAP: block idle while the UART is transferring data in
PIO mode"). This is because the OMAP UART driver's ->suspend()
callback is never called. The ->suspend() callback would have called
uart_suspend_port() which in turn would call enable_irq_wake(). Since
enable_irq_wake() isn't called for the UART's IRQ, check_wakeup_irqs()
would mask off the UART IRQ in the GIC.
On v3.3 kernels prior to the above commit, serial resume from suspend
presumably occurred via the PRCM interrupt. The UART was in
smart-idle mode, so it was able to send a PRCM wakeup which in turn
would be converted into a PRCM interrupt to the GIC, waking up the
kernel. But after the above commit, when the system is suspended in
the middle of a UART transmit, the UART IP block would be in no-idle
mode. In no-idle mode, the UART won't generate wakeups to the PRCM
when incoming characters are received; only GIC interrupts. But since
the UART driver's ->suspend() callback is never called,
uart_suspend_port() and enable_irq_wake() is never called; so the UART
interrupt is masked by check_wakeup_irqs() and the UART can't wake up
the MPU.
The remaining mechanism that could have awakened the system would have
been I/O chain wakeups. These wouldn't be active because the console
UART's clocks are never disabled when no_console_suspend is used,
preventing the full chip from idling. Also, current mainline doesn't
yet support full chip idle states for OMAP4, so I/O chain wakeups are
not enabled.
This patch is the result of a collaboration. John Stultz
<johnstul@us.ibm.com> and Andy Green <andy.green@linaro.org> reported
the serial wakeup problem that led to the discovery of this problem.
Kevin Hilman <khilman@ti.com> narrowed the problem down to the use of
no_console_suspend.

Currently all omap_devices are forced to have the dummy device
'omap_device_parent' as a parent. This was used to distinguish
omap_devices from "normal" platform_devices in the OMAP PM core code.
Now that we implement the PM core using PM domains, this is no longer
needed, and is removed.
This also frees up omap_devices to have a more complex parent/child
relationships that model actual device relationships.
The only in-tree user of omap_device_parent was the OMAP PM layer to
handle lost-context count for omap_devices. That is now converted to
use the presence of the omap_device_pm_domain instead.

To set sr ntarget values for all volt_domain,
volt_table is retrieved by doing a look_up of 'vdd_name'
field from omap_hwmod but voltage domain pointer does not
belong to omap_hwmod and is not used anywhere else.
As a part of voltage layer and SR Layer clean up volt
pointer is removed from omap_hwmod and added in dev
attributes of SR. The value of the field must match
the voltage domain names for the binding to be effective.
Tested on OMAP3630 SDP, OMAP3530 Beagleboard and
OMAP4430 SDP Board.

This functionality has already been implemented in the cx20442 codec
driver (commit f75a8ff67d161b5166a2c2360bb2ffaefd5eb853, "ASoC: cx20442:
add bias control over a platform provided regulator"), no need to keep
it here duplicated.
Once done, remove the no longer used AMS_DELTA_LATCH2_MODEM_NRESET
symbol from the board header file and a call to the regulator_toggle()
helper function from the old API wrapper found in the board file. While
being at it, simplify the way the modem .pm callback handles the
regulator and drop that helper function and its related consumer setup
completely.
Depends on patches 1/3 and 2/3 for clean apply and keep things working.

ARM: OMAP4: PRM: use PRCM interrupt handler
introduced the PRCM interrupt handler and thus the need
for 64 more interrupts. Since SPARSE_IRQ is still not fully
functional on OMAP, the NR_IRQS needs to be updated to avoid
the failure that happen during irq_alloc_descs call inside
the PRCM driver:
[ 0.208221] PRCM: failed to allocate irq descs: -12
Later the mux framework is then unable to request an IRQ from
the PRCM interrupt handler.
[ 1.802795] mux: Failed to setup hwmod io irq -22
Fix that by adding 64 more interrupts for OMAP2PLUS config.

Drivers should no longer use omap_read/write functions
but instead use ioremap + read/write functions.
As some USB legacy code is still shared between omap1 and
omap2420, let's limit the omap_read/write to plat/usb.h.
Note that the long term fix is to update the drivers to
use ioremap and read/write functions. That can now be
done as a separate patch series that is limited to the
USB drivers.
Also make sure the legacy omap1-keypad.c driver builds
if selected for 2420 based systems.

LCD config for old omapfb driver is passed with OMAP_TAG_LCD from board
files or from the bootloader. In an effort to remove OMAP_TAG_LCD, this
patch adds omapfb_set_lcd_config() function that the board files can
call to set the LCD config.
This has the drawback that configuration can no longer come from the
bootloader. Of the boards supported by the kernel, this should only
affect N770 which depends on the data from the bootloader. This patch
adds an LCD config for N770 to its board files, but that is most
probably broken. Fixing this would need information about the HW setup
in N770 boards.

In an effort to clean up the old omapfb driver, this patch removes
HWA742 (the display chip used in N770) platform data. This can be done
as N770 is the only user of HWA742, and the platform data contains only
one field, te_connected, which we can just presume to be true in the
HWA742 driver.
This allows us to remove omapfb_set_ctrl_platform_data(), and the
mechanism to pass the platform data, in a later patch.
