Hi

a few minor comments

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.

Sure. I will do that.

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

Okay.
