ST Ericsson abx500 pinmux controller
Required properties:
- compatible: “stericsson,ab8500-gpio”, “stericsson,ab8540-gpio”,
"stericsson,ab8505-gpio", "stericsson,ab9540-gpio",
Please refer to pinctrl-bindings.txt in this directory for details of the
common pinctrl bindings used by client devices, including the meaning of the
phrase “pin configuration node”.
ST Ericsson’s pin configuration nodes use the generic pin multiplexing
and pin configuration bindings, see pinctrl-bindings.txt
