ARM: EXYNOS: Add flush_cache_all in suspend finisher
ARM: EXYNOS: Remove scu_enable from cpuidle
ARM: EXYNOS: Fix soft reboot hang after suspend/resume
ARM: EXYNOS: Add support for rtc wakeup
ARM: EXYNOS: fix the hotplug for Cortex-A15

The core cpu_suspend code no longer calls flush_cache_all to
optimize the cpu idle flow. Add a call for the same in the
exynos specific suspend code.

Commit c9e4412ab8eb8ef82d645d8749c4ce96ad490007 removed all of the USB
PHY functions for OMAP4, but this causes a problem with core retention
as the MUSB module remains enabled if omap-usb2 phy driver is not used.
This keeps the USB DPLL enabled and prevents l3_init pwrdm from idling.
Fixed by adding a minimal function back that disables the USB PHY during

The OMAP port to the common clk framework[1] resulted in spurious WARNs
while disable unused clocks. This is due to _clkdm_clk_hwmod_disable
catching clkdm->usecount's with a value of zero. Even less desirable it
would not allow the clkdm_clk_disable function pointer to get called due
to an early return of -ERANGE.
This patch adds a check for such a corner case by skipping the WARN and
early return in the event that clkdm->usecount and clk->enable_usecount
are both zero. Presumably this could only happen during the check for
unused clocks at boot-time.

Platforms can call omap2_init_clk_hw_omap_clocks() to register a clock
using clk_hw_omap. omap2_clk_enable_autoidle_all() and
omap2_clk_disable_autoidle_all() can then be used to run through
all the clocks which support autoidle to enable/disable them.

OMAP2420 and OMAP2430 chips each have two on-chip APLLs. When locked,
one APLL generates a 96 MHz rate; the other, a 54 MHz rate.
Previously we treated these clocks as fixed-rate clocks at the locked
rates, but this isn't quite right. The locked rate should be returned
when the APLL is locked, and a zero rate should be returned when the
APLL is stopped. This patch adds the infrastructure that will be used
by the CCF changes.

Since commit edc88ceb0 (ARM: be really quiet when building with 'make -s') the
following output is generated when building a kernel for ARM:
echo ' Kernel: arch/arm/boot/Image is ready'
Kernel: arch/arm/boot/Image is ready
Building modules, stage 2.
echo ' Kernel: arch/arm/boot/zImage is ready'
Kernel: arch/arm/boot/zImage is ready
As per Documentation/kbuild/makefiles.txt the correct way of using kecho is
'@$(kecho)'.
Make this change so no more unwanted 'echo' messages are displayed.

to COMMON clk and get rid of all old/legacy code.
This converts all apis which will be called directly from COMMON
clk to take a struct clk_hw parameter, and all the internal platform
apis to take a struct clk_hw_omap parameter.

plat/clock.c which has most of usecounting/locking infrastructure will
be used only for OMAP1 until that is moved to use COMMON clk.
reuse most of what plat/clock.h has while we move to common clk, and
move most of what 'struct clk' was as 'struct clk_hw_omap' which
will then be used to define platform specific parameters.
All usecounting/locking related variables from 'struct clk' are
dropped as they will not be used with 'struct clk_hw_omap'.

on omap4 again. Although it's getting rather late for these
changes for the -rc cycle, it is important as many devices
are using MUSB for charging and connectivity.
With the USB PHY changes, MUSB started using the newly added
drivers/usb/phy/omap-usb2.c driver introduced by commit
657b306a (usb: phy: add a new driver for omap usb2 phy)
that is using the newly introduced drivers/bus/omap-ocp2scp.c
introduced by commit 26a84b3e (drivers: bus: add a new driver
for omap-ocp2scp).
These changes allowed dropping a lot of PHY related code from
arch/arm/mach-omap2/omap_phy_internal.c and have it live in
the device driver like it should with commit c9e4412a (arm: omap:
phy: remove unused functions from omap-phy-internal.c).
However, MUSB on omap4 broke with these changes for legacy
platform data boot, and now only works with device tree for
omap4. Unfortunately we are still few critical bindings away
from being able to make omap4 usbale with device tree.
Fix the regression properly by adding platform data support
to the ocp2scp driver so we can avoid adding back the driver
code to arch/arm/mach-omap2.
