Cavium ThunderX/OCTEON-TX GPIO controller bindings
|
|
Required Properties:
|
- reg: The controller bus address.
|
- gpio-controller: Marks the device node as a GPIO controller.
|
- #gpio-cells: Must be 2.
|
- First cell is the GPIO pin number relative to the controller.
|
- Second cell is a standard generic flag bitfield as described in gpio.txt.
|
|
Optional Properties:
|
- compatible: "cavium,thunder-8890-gpio", unused as PCI driver binding is used.
|
- interrupt-controller: Marks the device node as an interrupt controller.
|
- #interrupt-cells: Must be present and have value of 2 if
|
"interrupt-controller" is present.
|
- First cell is the GPIO pin number relative to the controller.
|
- Second cell is triggering flags as defined in interrupts.txt.
|
|
Example:
|
|
gpio_6_0: gpio@6,0 {
|
compatible = "cavium,thunder-8890-gpio";
|
reg = <0x3000 0 0 0 0>; /* DEVFN = 0x30 (6:0) */
|
gpio-controller;
|
#gpio-cells = <2>;
|
interrupt-controller;
|
#interrupt-cells = <2>;
|
};
