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.
