Subject: [PATCH 3/3] pinctrl: single: AM437x: Add pinctrl compatibility

From: Keerthy <j-keerthy@...com>

AM437x pinctrl definitions now differ from traditional 16 bit OMAP pin
ctrl definitions, in that all 32 bits are used to describe a single pin

Also the location of wakeupenable and event bits have changed.
