   1 Qualcomm Snapdragon GPIO controller
   2
   3 Required properties:
   4 - compatible : "qcom,msm8916-pinctrl" or "qcom,apq8016-pinctrl"
   5 - reg : Physical base address and length of the controller's registers.
   6         This controller is called "Top Level Mode Multiplexing" in
   7         Qualcomm documentation.
   8 - #gpio-cells : Should be one (pin number).
   9 - gpio-controller : Marks the device node as a GPIO controller.
  10 - gpio-count: Number of GPIO pins.
  11 - gpio-bank-name: (optional) name of gpio bank. As default "soc" is used.

  13 Example:
  14
  15 soc_gpios: pinctrl@1000000 {
  16         compatible = "qcom,msm8916-pinctrl";
  17         reg = <0x1000000 0x300000>;
  18         gpio-controller;
  19         gpio-count = <122>;
  20         gpio-bank-name="soc";
  21         #gpio-cells = <1>;
  22 };
