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.

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

In response, move the SCM headers into mach-omap2/.

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.

This fix is only a workaround. For a real fix, cpu_sibling_mask() should
be defined in UP include code, eg in linux/smp.h, and asm/smp.h should not be
included directly. This fix is currently not possible because asm/smp.h defines

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.

omap4: control: Add ctrl_pad_base to omap_globals
On omap4 control module is divided in four IP blocks.

- CTRL_MODULE_WKUP 0x4a30c000
- 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
The main control core base is still kept same in this patch to
keep git-bisect working. This will be fixed in the relevant patch
in this series.

OMAP4: clocks: Fix ES2 clock issues

- OPTFCLKEN_CLK32K is not handled anymore by the USBPHYOCP2SCP module in ES2

i.e. outside of code paths run when the device is not yet enabled or
already disabled. In particular, putting the device into D3hot is a
pretty bad idea when it was already brought up.
Furthermore, all prior callers of the function made sure they're
actually dealing with a PCI device, while the newly added one didn't.
