Kernel-3.10.0-957.el7_gpio-ms

MSM GPIO controller bindings

Required properties:

• compatible:
  • “qcom,msm-gpio” for MSM controllers
• #gpio-cells : Should be two.
  • first cell is the pin number
  • second cell is used to specify optional parameters (unused)
• gpio-controller : Marks the device node as a GPIO controller.
• #interrupt-cells : Should be 2.
• interrupt-controller: Mark the device node as an interrupt controller
• interrupts : Specify the TLMM summary interrupt number
• ngpio : Specify the number of MSM GPIOs

Example:

msmgpio: gpio@fd510000 {
    compatible = "qcom,msm-gpio";
    gpio-controller;
    #gpio-cells = <2>;
    interrupt-controller;
    #interrupt-cells = <2>;
    reg = <0xfd510000 0x4000>;
    interrupts = <0 208 0>;
    ngpio = <150>;
};
