Can we add a comment about this being the non-QE/CPM/GUTs GPIO
support. And maybe a reference to the 8349 as an example of the
controller if unsure about the compatibility.
Also, does it make sense to have a reference to the top-level generic
GPIO info w/regards to pin specific info, etc..
+Required properties:
+- compatible : "fsl,<CHIP>-gpio" followed by "fsl,mpc8349-gpio" for
+ 83xx, "fsl,mpc8572-gpio" for 85xx and "fsl,mpc8610-gpio" for 86xx.
+- #gpio-cells : Should be two. The first cell is the pin number and
the
+ second cell is used to specify optional parameters (currently
unused).
+ - interrupts : Interrupt mapping for GPIO IRQ (currently unused).
+ - interrupt-parent : Phandle for the interrupt controller that
+ services interrupts for this device.
+- gpio-controller : Marks the port as GPIO controller.
