This patch adds SAR RAM support on OMAP4430. SAR RAM used to save
and restore the HW context in low power modes.

The power management code needs to have access to enable/disable the
gic cpu interface and distributor based on targetted low power
states.
These APIs are suppose to me moved to common ARM GIC library and patch
for the same was posted earlier. The GIC code refactoring is ongoing
and hence for
This patch adds OMAP WakeupGen support. The WakeupGen unit is responsible
for generating wakeup event from the incoming interrupts and enable bits.
The WakeupGen is implemented in MPU Always-On power domain. During normal
operation, WakeupGen delivers external interrupts directly to the GIC.
When
On OMAP4 CPUidle, the low power states are triggered when CPU1
is offlined to OFF power state. When the CPU1 is online, no
low power states are supported.
The patch adds CPU hotplug notifier to manage the C-state
states using CPUidle prepare() hook and CPUIDLE_FLAG_IGNORE
c-state flag.
This was
CPU local timer(TWD) stops when the CPU is transitioning into
deeper C-States. Since these timers are not wakeup capable, we
need the wakeup capable global timer to program the wakeup time
depending on the next timer expiry.
It can be handled by registering a global wakeup capable timer along
OMAP L2X0 and GIC initialisation code uses BUG_ON() for the
ioremap() failure scenarios.
Use WARN_ON() instead and allow graceful function exits.
This was suggsted by Kevin Hilman khil...@ti.com during
OMAP4 PM code review.

The HW superwised smart idle for wdtimer in OMAP3 prevents
CORE power domain idle transitions. Disable it by swithing
to SW supervised transitions.
This could be a hardware bug in the OMAP3 wdtimer2 block.

You can map clock nodes to clkops_omap2_dflt_wait clkops instead of the

1. In ti_hecc_xmit(), data is not initialized, causing
undesirable effects like setting the RTR field for every
transmit.
2. In ti_hecc_probe(), the spinlock priv-mbx_lock is not
inited, causing a spinlock lockup BUG.

I think it should be 75 at most, which is also default for fmt.
git log idents the comment by 4 spaces, and it would be nice to have
