1ZTE ZX296702 GPIO controller
2
3Required 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.
