The supply is connected to the DSS DO-D5 pins and is thus needed for
both serial and parallel display interfaces on the igep0030 as well as
the igep0020.

If the igep0030 module isn't connected to a display, no DSI or DPI
display will be specified in board code, and the DSS driver won't enable

Each irq_chip for the main interrupt controller has offsets set for irq
masking registers, which added to respective base results in a pointer
to appropriate hardware register. However this is not correct for
INTC_CONTROL as there is only one INTC_CONTROL register. This does not
cause problems because generic ack code is never called, but remove
this assignment to avoid confusion.

Without runtime PM enabled, hwmod needs to leave all IP blocks in an
enabled state by default so any driver access to the HW will succeed.
This is accomplished by seting the postsetup_state to enabled for all
hwmods during init when runtime PM is disabled.

Currently, we have a special case for WDT in that its postsetup_state
is always set to disabled.  This is done so that the WDT is disabled
and the timer is disarmed at boot in case there is no WDT driver.
This also means that when runtime PM is disabled, if a WDT driver *is*
built in the kernel, the kernel will crash on the first access to the
WDT hardware.

We can't simply leave the WDT module enabled, because the timer is
armed by default after reset. That means that if there is no WDT
driver initialzed or loaded before the timer expires, the kernel will
reboot.

To fix this, a custom reset method is added to the watchdog class of
omap_hwmod.  This method will *always* disarm the timer after hwmod
reset.  The WDT timer then will only be rearmed when/if the driver is
loaded for the WDT.  With the timer disarmed by default, we no longer
need a special-case for the postsetup_state of WDT during init, so it
is removed.

Any platforms wishing to ensure the watchdog remains armed across the
entire boot boot can simply disable the reset-on-init feature of the
watchdog hwmod using omap_hwmod_no_setup_reset().

Tested on 3530/Overo, 4430/Panda.

NOTE: on 4430, the hwmod OCP reset does not seem to rearm the timer as
documented in the TRM (and what happens on OMAP3.)  I noticed this
because testing the HWMOD_INIT_NO_RESET feature with no driver loaded,
I expected a reboot part way through the boot, but did not see a
reboot.  Adding some debug to read the counter, I verified that right
after OCP softreset, the counter is not firing.  After writing the
magic start sequence, the timer starts counting.  This means that the
timer disarm sequence added here does not seem to be needed for 4430,
but is technically the correct way to ensure the timer is disarmed, so
it is left in for OMAP4.

Special thanks to Paul Walmsley for helping brainstorm ideas to fix
this problem.

The init for 3505/3517 specific clocks depends on the ordering of

checks for cpu_is_omap3505()).

Remove the 3505-specific checking since CK_3505 flag is not used, and
treat all AM35x clocks the same.

This means that the SGX clock (the only AM35x clkdev not currently
flagged for 3505) will now be registered on 3505, but that is
harmless.  That can be cleaned up when the clkdev nodes are removed in
favor of them being registered by hwmod.

verify_parent_transid needs to lock the extent range to make
sure no IO is underway, and so it can safely clear the
uptodate bits if our checks fail.

But, a few callers are using it with spinlocks held.  Most
of the time, the generation numbers are going to match, and
we don't want to switch to a blocking lock just for the error
case.  This adds an atomic flag to verify_parent_transid,
and changes it to return EAGAIN if it needs to block to
properly verifiy things.
