     1 ZTE ZX296702 GPIO controller
    2 
    3 Required properties:
    4 - compatible : "zte,zx296702-gpio"
    5 - #gpio-cells : Should be two. The first cell is the pin number and the
    6   second cell is used to specify optional parameters:
    7   - bit 0 specifies polarity (0 for normal, 1 for inverted)
    8 - gpio-controller : Marks the device node as a GPIO controller.
    9 - interrupts : Interrupt mapping for GPIO IRQ.
   10 - gpio-ranges : Interaction with the PINCTRL subsystem.
