- "ti,omap2-gpio" for OMAP2 controllers
- "ti,omap3-gpio" for OMAP3 controllers
- "ti,omap4-gpio" for OMAP4 controllers
+- gpio-controller : Marks the device node as a GPIO controller.
- #gpio-cells : Should be two.
- first cell is the pin number
- second cell is used to specify optional parameters (unused)
-- gpio-controller : Marks the device node as a GPIO controller.
+- interrupt-controller: Mark the device node as an interrupt controller.
- #interrupt-cells : Should be 2.
-- interrupt-controller: Mark the device node as an interrupt controller
The first cell is the GPIO number.
The second cell is used to specify flags:
bits[3:0] trigger type and level flags:
gpio4: gpio4 {
compatible = "ti,omap4-gpio";
ti,hwmods = "gpio4";
- #gpio-cells = <2>;
gpio-controller;
- #interrupt-cells = <2>;
+ #gpio-cells = <2>;
interrupt-controller;
+ #interrupt-cells = <2>;
