Using the platform driver model is a good way to separate the cpuidle specific
code from the low level pm code. It allows to remove the dependency between
these two components.

The platform_device is located in the pm code and a 'set' function has been
added to set the standby function from the AT91_SOC_START initialization
function. Each SoC with a cpuidle driver will set the standby function in the
platform_data field at init time. Then pm code will register the cpuidle
platform device.

The cpuidle driver will register the platform_driver and use the device's
platform_data as a standby callback in the idle path.

The at91_pm_enter function contains a { if then else } based on cpu_is_xx
similar to what was in cpuidle. This is considered dangerous when adding a new
SoC. Like the cpuidle driver, a standby ops is defined and assigned when the
SoC init function specifies what is its standby function and reused in the
at91_pm_enter's 'case' block.

HWMOD removal for MMC is breaking edma_start as the events are being manually
triggered due to unused channel list not being clear.

The above issue is fixed by reading the "dmas" property from the DT node if it
exists and clearing the bits in the unused channel list if the dma controller
used by any device is EDMA. For this purpose we use the of_* helpers to parse
the arguments in the dmas phandle list.

Also introduced is a minor clean up of a checkpatch error in old code.

On the TC2 testchip, when all CPUs in a cluster enter standbywfi
and commit a power down request, the power controller will wait
for standbywfil2 coming from L2 cache controller to shut the
cluster down.
By the time all CPUs in a cluster commit a power down request
and enter wfi, the power controller cannot backtrack, or put it
another way, a CPU must not be allowed to complete execution
independently of the power controller, the only way for it to
resume properly must be upon wake-up IRQ pending and subsequent
reset triggered from the power controller.

Current MCPM back-end for TC2 disables the GIC CPU IF only when
power down is committed through the tc2_pm_suspend() method, that
makes sense since a suspended CPU is still online and can receive
interrupts whereas a hotplugged CPU, since it is offline,
migrated all IRQs and shutdown the per-CPU peripherals, hence
their PPIs.

The flaw with this reasoning is the following. If all CPUs in
a clusters are entering a power down state either through CPU
idle or CPU hotplug, when the last man successfully completes
the MCPM power down sequence (and executes wfi), power controller
waits for L2 wfi signal to quiesce the cluster and shut it down.
If, when all CPUs are sitting in wfi, an online CPU hotplugs back
in one of the CPUs in the cluster being shutdown, that CPU
receives an IPI that causes wfi to complete (since tc2_pm_down()
method does not disable the GIC CPU IF in that case - CPU being
hotplugged out, not idle) and the power controller will never see
the stanbywfil2 signal coming from L2 that is required for
shutdown to happen and the system deadlocks.

Further to this issue, kexec hotplugs secondary CPUs out during
kernel reload/restart.
Because kexec may (deliberately) trash the old kernel text, it is
not OK for CPUs to follow the MCPM soft reboot path, since
instructions after the WFI may have been replaced by kexec.

If tc2_pm_down() does not disable the GIC cpu interface, there is a
race between CPU powerdown in the old kernel and the IPI from the
new kernel that triggers secondary boot, particularly if the
powerdown is slow (due to L2 cache cleaning for example).  If the
new kernel wins the race, the affected CPU(s) will not really be
reset and may execute garbage after the WFI.

The only solution to this problem consists in disabling the GIC
CPU IF on a CPU committed to power down regardless of the power
down entry method (CPU hotplug or CPU idle). This way, CPU wake-up
is under power controller control, which prevents unexpected wfi
exit caused by a pending IRQ.

This patch moves the GIC CPU IF disable call in the TC2 MCPM
implementation from the tc2_pm_suspend() method to the
tc2_pm_down() method to fix the mentioned race condition(s).

Commit 377747c4 ("ARM: entry: allow ARM-private syscalls to be

restarting of ARM-private syscalls. Unfortunately, this relocated the
label used to dispatch a private syscall from the trace path, so that
the invocation would be bypassed altogether!

This causes applications to fail under strace as soon as they rely on
a private syscall (e.g. set_tls):

  set_tls(0xb6fad4c0, 0xb6fadb98, 0xb6fb1050, 0xb6fad4c0, 0xb6fb1050)
      = -1 ENOSYS (Function not implemented)

Currently on the Lager board NFS timeouts/delays are seen when booting.  That
turned out to happen because the SoC's ETH_LINK signal turns on and off after
each packet.  It is connected to Micrel KSZ8041 PHY's LED0 signal. Ether LEDs
on the Lager board are named LINK and ACTIVE which corresponds to non-default
01 setting of the PHY control register 1 bits 14-15. The 'sh_eth' driver resets
the PHY when opening the network device, so we have to set the mentioned bits
back to 01 from the default 00 value which causes bouncing of ETH_LINK.  That
can be achieved using the PHY platform fixup mechanism if we also modify the
driver to use it..

It is supposed that sar_base is initialized in irq_save_context, which
is called on CPU_CLUSTER_PM_ENTER notification. If this notification
has been missed and CPU_CLUSTER_PM_EXIT is received sar_base is NULL.

Fix it by calling CPU_CLUSTER_PM_{ENTER,EXIT} under the same condition.

When CONFIG_ARM_LPAE=y the following build warning is generated:

arch/arm/mach-omap2/gpmc.c:1495:4: warning: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'resource_size_t' [-Wformat]

According to Documentation/printk-formats.txt '%pa' can be used to properly
print 'resource_size_t'.

In case of error, the function omap_device_alloc() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check
should be replaced with IS_ERR().
