After going round-n-round on how to add support for AM33XX family
of device into kernel, especially for PRM and CM support, we have
decided to handle it 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, soon I will
have similar patch for CM support, then clock-tree and hwmod will follow...
Changes 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.

ARM: OMAP3/4: omap_hwmod: Add rstst_off field to struct
omap_hwmod_omap4_prcm
ARM: OMAP2+: powerdomain: Add offset & mask fields to struct
powerdomain
ARM: OMAP3+: am33xx: Add power domain data
