bf56f0a666 omap4: pandaboard: fix up mmc card detect logic
For MMC1 Controller, card detect interrupt source is
twl6030 which is non-gpio. The card detect call back function provides
card present/absent status by reading MMC Control register present
on twl6030. This functionality was introduced in mfd tree on
track to kernel.org

Sync pandaboard to the same and make mmc work.

72f2e2c763 mfd: Adding twl6030 mmc card detect support for MMC1
Adding card detect callback function and card detect configuration
function for MMC1 Controller on OMAP4.

Card detect configuration function does initial configuration of the
MMC Control & PullUp-PullDown registers of Phoenix.

For MMC1 Controller, card detect interrupt source is
twl6030 which is non-gpio. The card detect call back function provides
card present/absent status by reading MMC Control register present
on twl6030.

Since OMAP4 doesn't use any GPIO line as used in OMAP3 for card detect,
the suspend/resume initialization which was done in omap_hsmmc_gpio_init
previously is moved to the probe thus making it generic for both OMAP3 &
OMAP4.

0ea1293009 arm: return both physical and virtual addresses from addruart
Rather than checking the MMU status in every instance of addruart, do it
once in kernel/debug.S, and change the existing addruart macros to
return both physical and virtual addresses. The main debug code can then
select the appropriate address to use.

This will also allow us to retreive the address of a uart for the MMU
state that we're not current in.

-------------------------------------

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.

de65815860 OMAP3: PM: fix scratchpad memory accesses for off-mode
Commit 914bab936fe0388a529079679e2f137aa4ff548d (OMAP: mach-omap2: Fix
incorrect assignment warnings) changed a pointer from 'u32 *' to
'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.

Special thanks to Jean Pihet for taking the time track down this
problem and propose an initial solution.

Tested with off-idle and off-suspend on 36xx/Zoom3 and 34xx/omap3evm.

6041c27f51 OMAP2+: clock: reduce the amount of standard debugging while disabling unused clocks
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
production kernels with debug-level messages enabled reported that the
large number of clock disable messages were slowing boot.  Now to
enable clock-by-clock disable messages, DEBUG needs to be defined in
mach-omap2/clock.c.

4814ced511 OMAP: control: move plat-omap/control.h to mach-omap2/control.h
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.

aa218dafd7 OMAP: split plat-omap/common.c
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.

Benoît Cousson <b-cousson@ti.com> suggested a new filename and found
some bugs in the counter_32k.c comments - thanks Benoît.

d13586574d OMAP: McBSP: implement functional clock switching via clock framework
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.

cf4c87abe2 OMAP: McBSP: implement McBSP CLKR and FSR signal muxing via mach-omap2/mcbsp.c
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.
Due to the unfortunate way that McBSP support is implemented in ASoC
and the OMAP tree, these symbols must be exported for use by
sound/soc/omap/omap-mcbsp.c.

Going forward, the McBSP device driver should be moved from

Fix this by making the boards depend on the Kconfig option for the

Also, while here, fix the mach-omap2/board-generic.c file to remove the
dependency on OMAP2420.

20252d4659 OMAP2PLUS: WDT: Fix: Disable WDT after reset during init
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.
