[PATCH-V4 0/4] ARM: OMAP2+: Add voltagedomain, powerdomain & PRM support for AM33XX device

[Vaibhav Hiremath]

After some healthy discussion, now we have come to the conclusion and
decided to handle AM33XX PRM/CM part separately; as AM33XX-PRCM module is
different than OMAP3 and OMAP4 architecture.

The difference becomes very interesting/weird when it comes to
the consistency for register offsets in PRM address space and
bit-field offsets inside PRM registers,
So along with Powerdomain data and PRM api's required for AM33XX
device, this patch series adds,

 - XXX_RSTST register offset to "struct omap_hwmod_omap4_prcm"
 - PWRSTCTRL & PWRSTST register offsets to "struct powerdomain"
 - Logicretstate and mem_on/ret/pwrst/retst mask to "struct
   powerdomain"

Testing: This patch series has been boot tested on AM37xEVM and AM335x
         based BeagleBone community board.

Thanks to Paul here...for helping and concluding on this,
shortly I will submit similar patch for CM, clockdomain and clock-tree
support for AM33xx.

This patch-series is created on top of "linux-omap/cleanup" branch, and
also gets applied to "linux-omap/master" branch.

Changes from previous versions:
===============================
>From V3:
	- No code change, only added Voltagedomain patch (from V2 series)
	  to this series.

>From V1 & V2:
    	- Rolled back to my original approach, where AM33xx
	  device was handled separately (RFC version).
	- As per Paul's comments, added Register offsets & bit-fields
	  masks.
