-* Freescale i.MX/MXC GPIO controller
-
-Required properties:
-- compatible : Should be "fsl,<soc>-gpio"
-- reg : Address and length of the register set for the device
-- interrupts : Should be the port interrupt shared by all 32 pins, if
- one number. If two numbers, the first one is the interrupt shared
- by low 16 pins and the second one is for high 16 pins.
-- gpio-controller : Marks the device node as a gpio controller.
-- #gpio-cells : Should be two. The first cell is the pin number and
- the second cell is used to specify the gpio polarity:
- 0 = active high
- 1 = active low
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells : Should be 2. The first cell is the GPIO number.
- The second cell bits[3:0] is used to specify trigger type and level flags:
- 1 = low-to-high edge triggered.
- 2 = high-to-low edge triggered.
- 4 = active high level-sensitive.
- 8 = active low level-sensitive.
-
-Optional properties:
-- clocks: the clock for clocking the GPIO silicon
-
-Example:
-
-gpio0: gpio@73f84000 {
- compatible = "fsl,imx51-gpio", "fsl,imx35-gpio";
- reg = <0x73f84000 0x4000>;
- interrupts = <50 51>;
- gpio-controller;
- #gpio-cells = <2>;
- interrupt-controller;
- #interrupt-cells = <2>;
-};
