Currently, the exynos cpuidle driver works correctly only on exynos4210

While powering on/off a local powerdomain in exynos5 chipsets, the
input clocks to each device gets modified. This behaviour is based
on the SYSCLK_SYS_PWR_REG registers.
E.g. SYSCLK_MFC_SYS_PWR_REG = 0x0, the parent of input clock to MFC
(aclk333) gets modified to oscclk
= 0x1, no change in clocks.
The recommended value of SYSCLK_SYS_PWR_REG before power gating any
domain is 0x0. So we must also restore the clocks while powering on
a domain everytime.
This patch adds the framework for getting the required mux and parent
clocks through a power domain device node. With this patch, while
powering off a domain, parent is set to oscclk and while powering back
on, its re-set to the correct parent which is as per the recommended
pd on/off sequence.

Merge tag 'for-v3.16-rc/omap-fixes-b' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.16/fixes
Some miscellaneous fixes for OMAP clock code, DRA7xx device data, and
PRCM code (when DSPBridge is used) for v3.16-rc.
Basic build, boot, and PM test logs are available here:
http://www.pwsan.com/omap/testlogs/prcm-a-v3.16-rc/20140706174258/
Let's say clock A and B are two gate clocks that share the same register
bit in hardware. Therefore they are registered as shared gate clocks
with imx_clk_gate2_shared().
In a scenario that only clock A is enabled by clk_enable(A) while B is
not used, the shared gate will be unexpectedly disabled in hardware.
It happens because clk_enable(A) increments the share_count from 0 to 1,
while clock B is unused to clock core, and therefore the core function
will just disable B by calling clk->ops->disable() directly. The
consequence of that call is share_count is decremented to 0 and the gate
is disabled in hardware, even though clock A is still in use.
The patch fixes the issue by initializing the share_count per hardware
state and returns enable state per share_count from .is_enabled() hook,
in case it's a shared gate.
While at it, add a check in clk_gate2_disable() to ensure it's never
called with a zero share_count.

After clarification from the hardware team it was found that
this 1.8V PHY supply can't be switched OFF when SoC is Active.
Since the PHY IPs don't contain isolation logic built in the design to
allow the power rail to be switched off, there is a very high risk
of IP reliability and additional leakage paths which can result in
additional power consumption.
The only scenario where this rail can be switched off is part of Power on
reset sequencing, but it needs to be kept always-on during operation.
This patch is required for proper functionality of USB, SATA
and PCIe on DRA7-evm.

This week's arm-soc fixes:
- A set of of OMAP patches that we had missed Tony's pull request of:
- Reset fix for am43xx
- Proper OPP table for omap5
- Fix for SoC detection of one of the DRA7 SoCs
- hwmod updates to get SATA and OCP to work on omap5 (drivers merged in 3.16)
- ... plus a handful of smaller fixes
- sunxi needed to re-add machine specific restart code that was removed in
anticipation of a watchdog driver being merged for 3.16, and it didn't make
it in.
- Marvell fixes for PCIe on SMP and a big-endian fix.
- A trivial defconfig update to make my capri test board boot with
bcm_defconfig again.
... and a couple of MAINTAINERS updates, one to claim new Keystone
drivers that have been merged, and one to merge MXS and i.MX (both

The largest diffs come from the hwmod code for omap5 and the re-add of
the restart code on sunxi. The hwmod stuff is quite late at this point
but it slipped through cracks repeatedly while coming up the maintainer
chain and only affects the one SoC so risk is low.

This partly reverts commits 553600502b (ARM: sunxi: Remove reset code from
the platform) and 5e669ec583 (ARM: sunxi: Remove init_machine callback) for
the sun4i, sun5i and sun7i families.
This is needed because the watchdog counterpart of these commits was dropped,
and didn't make it into 3.16. In order to still be able to reboot the board, we
need to reintroduce that code. Of course, the long term view is still to get
rid of that code in mach-sunxi.

This patch registers the exynos mct clocksource as the current timer
as it has constant clock rate. This will generate correct udelay for
the exynos platform and avoid using unnecessary calibrated
jiffies. This change has been tested on exynos5420 based board and
udelay is very close to expected.
Without this patch udelay() on exynos5400 / exynos5800 is wildly
inaccurate due to big.LITTLE not adjusting loops_per_jiffy correctly.
Also without this patch udelay() on exynos5250 can be innacruate
during transitions between frequencies < 800 MHz (you'll go 200 MHz ->
800 MHz -> 300 MHz and will run at 800 MHz for a time with the wrong
loops_per_jiffy).

In (93bfb76 clocksource: exynos_mct: register sched_clock callback) we
supported using the MCT as a scheduler clock. We properly marked
exynos4_read_sched_clock() as notrace. However, we then went and
called another function that _wasn't_ notrace. That means if you do:
cd /sys/kernel/debug/tracing/
echo function_graph > current_tracer
You'll get a crash.
Fix this (but still let other readers of the MCT be trace-enabled) by
adding an extra function. It's important to keep other users of MCT
traceable because the MCT is actually quite slow to access and we want
exynos4_frc_read() to show up in ftrace profiles if it's the
bottleneck.

The CurrentEL system register reports the Current Exception Level
of the CPU. It doesn't say anything about the stack handling, and
yet we compare it to PSR_MODE_EL2t and PSR_MODE_EL2h.
It works by chance because PSR_MODE_EL2t happens to match the right
bits, but that's otherwise a very bad idea. Just check for the EL
value instead.
