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
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
conversion.

OMAP3xxx: clock: add clkdev aliases for McBSP fclk source switching

The OMAP3 clock tree already contains the infrastructure to support
clock framework-based McBSP functional clock source switching. But it
did not contain the clkdev aliases for the McBSP code to refer to the
parent clocks in an SoC integration-neutral way. So, add the clkdev
aliases for the parent clocks.

OMAP2+: Kconfig: disallow builds for boards that don't use the currently-selected SoC

Currently, if, for example, CONFIG_ARCH_OMAP2420 is not selected, OMAP2420
board files can still be included in the build. This results in link errors:

arch/arm/mach-omap2/built-in.o: In function `omap_generic_map_io':

make: *** [.tmp_vmlinux1] Error 1

Fix this by making the boards depend on the Kconfig option for the
specific SoC that they use.

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

omap: Update omap2plus_defconfig to use ttyO instead ttyS

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]
to /etc/securetty.

OMAP2: PM: check UART status before trying to idle

As is done on OMAP3, check omap_uart_can_sleep() as one of the
pre-conditions for entering the idle loop. Without this check,
entering idle introduces large latencies on active UARTs, and is
especially noticable on serial console.

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.

OMAP1: Amstrad Delta: add support for camera

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.

omap4 hsmmc: Update ocr mask for MMC2 for regulator to use

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.

Merge branch 'omap4_and_sdrc_2.6.27' of git://git.pwsan.com/linux-2.6 into omap-for-linus

omap3: Prevent SDRC deadlock when L3 is changing frequency

When changing the L3 clock frequency, the CPU is executing from internal RAM
and the SDRC clock is disabled. During this time accesses made to external
DDR are stalled. If the ARM subsystem attempts to access the DDR while the
SDRC clock is disabled this will stall the CPU until the access to the SDRC
timeouts. A timeout on the SDRC should never occur. Once a timeout occurs all
the following accesses will be aborted and the DDR is no longer accessible.

Although the code being executed in the internal RAM does not directly access
the DDR, it was found that the branch prediction logic in the CPU may cause
the CPU to prefetch code from a DDR location while the SDRC clock is disabled.
This was causing an SDRC timeout which resulted in a system hang.

This patch fixes this problem by ensuring the branch prediction logic is
disabled while changing the L3 clock frequency. The branch prediction logic
is disabled by clearing the Z-bit in the ARM CTRL register.

Disabling the branch prediction logic does not have any noticable impact
on the execution time of this code section. The hardware observability
signals were used to monitor the sdrc idle time with and without this
patch when operating at different CPU frequencies (150MHz, 500MHz and
600MHz) and the total sdrc idle time when changing frequenct was in
the range of 9-11us. This was measured on an omap3430 SDP running the
omapzoom p-android-omap-2.6.29 branch.

- CTRL_MODULE_PAD_WKUP 0x4a31e000

Addressing all the modules with single base address is not possible
considering 16 bit offsets. The mux code manages the pad core and pad
wakeup related base address inside the mux framework. For other usage
only control core and control pad bases are necessary. So this patch
maps only needed pad control base address which is used by device drivers
and infrastructure code

This patch updates the PRM and CM register bitshifts and masks
for OMAP4430 ES2.0.

Replace as well the BITFIELD macro with the shift operator in order
to be consistent with the previous OMAP2 & 3 format.

Sort the register list in comments in order to have a consistent
register order and avoid futur change during code generation.

OMAP4: clock: Add optional clock nodes

OMAP4 IP optional clocks require explicit enable in module CTRLCLK
register. In order to allow that we have to create artificial clock
nodes that represent this clock inputs in the IP.

Notes:
- Temporary use OMAP3 names for GPIO optional clocks until the GPIO hwmod
convertion is done. It will enforce the usage of OMAP4 names as the reference.
- Temporary use OMAP3 names for TIMER main clock (gptX_fck) until TIMER hwmod
convertion is done. During that convertion, the new name will have to be used.

OMAP4: clock: Fix clock names and align with hwmod names

The OMAP4 hwmod data introduced the new naming convention for TI
IPs (See patch OMAP4: hwmod: Add partial hwmod support for OMAP4430 ES1.0)

The leaf clock names are using the same IP name and thus must be
modified to match the clock populated in the hwmod data.

- Fix some leaf clocks nodes that were using a _iclk instead of the _fclk
prefix.
- Fix some wrong interface clock name for master IPs connected to
interconnect.

Please not that due to the fact that nodes are sorted by name, the name
change will introduce a quite ugly diff a little bit hard to follow.

Timers clock con_id is still using the old gptX_fck name until the
gptimer driver is updated to omap_device framework.
Timers entries in hwmods DB are still disabled until the migration
if timer to platform_driver + omap_hwmod.

omap2: McBSP: Remove mux code for OMAP2420 McBSP2 and do cleanups

This 'legacy' OMAP2420 McBSP2 muxing code is currently broken after recent
conversion to new mux code. The omap_mcbsp_request calling this code is
usually called after booting whereas the omap_mux_init_signal is __init
marked so null pointer dereference would occur.

Fix this by removing the muxing code and let the bootloader or board file to
do it if necessary. Remove also omap2_mcbsp_ops as there is no use for it.

omap: McBSP: Do not enable SRG in slave mode

McBSP SRG (Sample Rate Generator) and FSG (Frame Sync

In McBSP slave mode, the SRG, and FSG can be kept disabled,
which might save some power at the end in this configuration.
