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