| 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. |
