- compatible : "snps,dw-apb-gpio-port"
- gpio-controller : Marks the device node as a gpio controller.
-- #gpio-cells : Should be 1. It is the pin number.
+- #gpio-cells : Should be two. The first cell is the pin number and
+ the second cell is used to specify the gpio polarity:
+ 0 = active high
+ 1 = active low
