The patch series adds IO wake up support for AM437x series
making use of the existing OMAP4 support. Adds the AM437x
specifics.
The series is boot tested on OMAP4 panda, DAR7 evm and AM437x evms.
Changes in v2:
Removed inefficient way of using arrays for irq ack and masks.
Keerthy (6):
ARM: OMAP4: PRM: Remove hardcoding of PRM_IO_PMCTRL_OFFSET register
ARM: AM43xx: Add the PRM IRQ register offsets
ARM: dts: AM4372: Add PRCM IRQ entry
ARM: OMAP: PRM: Remove hardcoding of IRQENABLE_MPU_2 and
IRQSTATUS_MPU_2 register offsets
ARM: OMAP4+: PRM: Add AM437x specific data
ARM: PRM: AM437x: Enable IO wakeup feature

PRM_IO_PMCTRL_OFFSET need not be same for all SOCs hence
remove hardcoding and use the value provided by the omap_prcm_irq_setup
structure.

Please mention here that the reason why you're making this change is to
support AM437x.

Please add a kerneldoc structure documentation line for this new field, to
match the existing documentation here.

Please add more detail to your commit messages so they conform to
Documentation/SubmittingPatches:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/SubmittingPatches#n109
For example, this commit message should read something like:
---
ARM: AM43xx: Add the PRM IRQ register offsets
Add the PRM IRQ register offsets. This is needed to support PRM I/O
wakeup on AM43xx.
--
Basically, your patches need to provide context as to _why_ the change is
needed.
I've fixed the message for this patch, and queued it for v4.3, but
please take care with this issue in the future.

Also I've moved the AM43XX_PRM_IO_PMCTRL_OFFSET macro out of the AM43XX CM
section, since it doesn't belong there.

* [PATCH v2 4/6] ARM: OMAP: PRM: Remove hardcoding of IRQENABLE_MPU_2 and IRQSTATUS_MPU_2 register offsets

The register offsets of IRQENABLE_MPU_2 and IRQSTATUS_MPU_2 are hardcoded.
This makes it difficult to reuse the code for SoCs like AM437x that have
a single instance of IRQENABLE_MPU and IRQSTATUS_MPU registers.
Hence handling the case using offset of 4 to accommodate single set of IRQ*
registers generically.

The register offsets for some of the PRM Registers are different
hence populating the differing fields.
