An errata workaround for omap24xx is not setting the buffering disable bit
25 what is the purpose but channel enable bit 7 instead.
Background for this fix is the DMA stalling issue with ASoC omap-mcbsp
driver. Peter Ujfalusi <peter.ujfalusi@nokia.com> has found an issue in
recording that the DMA stall could happen if there were a buffer overrun
detected by ALSA and the DMA was stopped and restarted due that. This
problem is known to occur on both OMAP2420 and OMAP3. It can recover on
OMAP3 after dma free, dma request and reconfiguration cycle. However, on
OMAP2420 it seems that only way to recover is a reset.
Problem was not visible before the commit c12abc0. That commit changed that
the McBSP transmitter/receiver is released from reset only when needed. That
is, only enabled McBSP transmitter without transmission was able to prevent
this DMA stall problem in receiving side and underlying problem did not show
up until now. McBSP transmitter itself seems to no be reason since DMA
stall does not recover by enabling the transmission after stall.
Debugging showed that there were a DMA write active during DMA stop time and
it never completed even when restarting the DMA. Experimenting showed that
the DMA buffering disable bit could be used to avoid stalling when using
source synchronized transfers. However that could have performance hit and
OMAP3 TRM states that buffering disable is not allowed for destination
synchronized transfers so subsequent patch will implement a method to
complete DMA writes when stopping.
This patch is based on assumtion that complete lock-up on OMAP2420 is
different but related problem. I don't have access to OMAP2420 errata but
I believe this old workaround here is put for a reason but unfortunately
a wrong bit was typed and problem showed up only now.

This is happening because 'omap_serial_init()' is hanging in the boot.
On OMAP3 the watchdog is generating reboot because devices_init doesn't
happens where as on OMAP4 it just hangs without reboot.
The uart clock is not getting enabled after omap_device_idle as part
of omap_serial_init.
The omap_device_idle(will disable the clock) then omap_uart_block_sleep()
should enable clock back disabled during the boot up phase.
But omap_uart_block_sleep() stuffed version is binded only under
CONFIG_PM and other version is just empty. Hence it is not enabling
clock back as expected
This patch adds uart clock enable code to omap_uart_block_sleep() function
built with CONFIG_PM disabled.

'void *' without also fixing up the pointer arithmetic.
Fix the scratchpad offsets so they are byte offsets instead of
word offsets and thus work correctly with a void pointer base.

Reduce the amount of debugging generated by default when unused clocks
are being disabled by the clock code. The previous code would only
generate debug-level messages, but some people who wished to run

Only OMAP2+ platforms have the System Control Module (SCM) IP block.
In the past, we've kept the SCM header file in plat-omap. This has
led to abuse - device drivers including it; includes being added that
create implicit dependencies on OMAP2+ builds; etc.
In response, move the SCM headers into mach-omap2/.
As part of this, remove the direct SCM access from the OMAP UDC
driver. It was clearly broken. The UDC code needs an indepth review for
use on OMAP2+ chips.

Split plat-omap/common.c into three pieces:
1. the 32KiHz sync timer and clocksource code, which now lives in
plat-omap/counter_32k.c;
2. the OMAP2+ common code, which has been moved to mach-omap2/common.c;
3. and the remainder of the OMAP-wide common code, which includes the
deprecated ATAGs code and a deprecated video RAM reservation function.
The primary motivation for doing this is to move the OMAP2+-specific parts
into an OMAP2+-specific file, so that build breakage related to the
System Control Module code can be resolved.

Previously the OMAP McBSP ASoC driver implemented CLKS switching by
using omap_ctrl_{read,write}l() directly. This is against policy; the OMAP
System Control Module functions are not intended to be exported to drivers.
These symbols are no longer exported, so as a result, the OMAP McBSP ASoC
driver does not build as a module.
Resolve the CLKS clock changing portion of this problem by creating a
clock parent changing function that lives in
arch/arm/mach-omap2/mcbsp.c, and modify the ASoC driver to use it.
Due to the unfortunate way that McBSP support is implemented in ASoC
and the OMAP tree, this symbol must be exported for use by
sound/soc/omap/omap-mcbsp.c.
Going forward, the McBSP device driver should be moved from
arch/arm/*omap* into drivers/ or sound/soc/* and the CPU DAI driver
should be implemented as a platform_driver as many other ASoC CPU DAI
drivers are. These two steps should resolve many of the layering
problems, which will rapidly reappear during a McBSP hwmod/PM runtime
conversions.

The OMAP ASoC McBSP code implemented CLKR and FSR signal muxing via
direct System Control Module writes on OMAP2+. This required the
omap_ctrl_{read,write}l() functions to be exported, which is against
policy: the only code that should call those functions directly is
OMAP core code, not device drivers. omap_ctrl_{read,write}*() are no
longer exported, so the driver no longer builds as a module.
Fix the pinmuxing part of the problem by removing calls to
omap_ctrl_{read,write}l() from the OMAP ASoC McBSP code and
implementing signal muxing functions in arch/arm/mach-omap2/mcbsp.c.

With the omap-serial the device has changed from ttyS to ttyO as
the system may have both omap-serial and 8250 ports.
Note that systems using omap-serial need to be updated to use ttyO[012]
instead of ttyS[012] in the bootloader, CONFIG_CMDLINE, /etc/inittab,
and the root file system with mknod. Also you may need to add ttyO[012]

Inorder to avoid any assumptions from bootloader, the watchdog
timer module is reset during init. This enables the watchdog
timer.
Therefore, it is required to disable WDT after it is reset
during init. Otherwise the system would reboot as per the default
watchdog timer registers settings.
Later, when the watchdog driver is loaded, the watchdog timer settings
is adjusted as per the default timer_margin set in the driver and the
driver would supports the normal operations supported by OMAP watchdog
timer.

This patch extends the Amstrad Delta camera support with LEDS trigger that can
be used for automatic control of the on-board camera LED. The led turns on
automatically on camera device open and turns off on camera device close.

This patch adds configuration data and initialization code required for camera
support to the Amstrad Delta board.
Three devices are declared: SoC camera, OMAP1 camera interface and OV6650
sensor.
Default 12MHz clock has been selected for driving the sensor. Pixel clock has
been limited to get reasonable frame rates, not exceeding the board
capabilities. Since both devices (interface and sensor) support both pixel
clock polarities, decision on polarity selection has been left to drivers.
Interface GPIO line has been found not functional, thus not configured.

This patch adds a definition of the OMAP1 camera interface platform device,
and a function that allows for providing a board specific platform data.
The device will be used with the upcoming OMAP1 SoC camera interface driver.

On OMAP4, MMC2 controller has eMMC which draws power from VAUX regulator
on TWL. Though the eMMC supports dual voltage[1.8v/3v] as per ocr register,
its VCC is fixed at 3V for operation. With this once the mmc core selects
the minimum voltage[1.8] supported based on the ocr value read from OCR register,
eMMC will not get detected. Thus the platform data for MMC2 is updated with ocr
mask and same will be communicated to core which will set the regulator to
always operate at 3V when ever turned ON.

In OMAP4, as per new PM programming model, the legacy registers
which were there in OMAP3 are all shifted by 0x100 while new one's
are added from offset 0 to 0x10.
For OMAP4, the register offset appending of 0x100 done in devices.c
currently, is moved to driver file.This change fits in for current
implementation as well as once the driver undergoes hwmod adaptation.

The omap4 es2 hsmmc has a updated soft reset logic.After the
reset is issued monitor a 0->1 transition first. The reset of
CMD or DATA lines is complete only after a 0->1->0 transition
of SRC or SRD bits.
