Nomadik GPIO controller
|
||||
|
||||
Required properties:
|
||||
- compatible : Should be "st,nomadik-gpio".
|
||||
- reg : Physical base address and length of the controller's registers.
|
||||
- interrupts : The interrupt outputs from the controller.
|
||||
- #gpio-cells : Should be two:
|
||||
The first cell is the pin number.
|
||||
The second cell is used to specify optional parameters:
|
||||
- bits[3:0] 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.
|
||||
- gpio-controller : Marks the device node as a GPIO controller.
|
||||
- interrupt-controller : Marks the device node as an interrupt controller.
|
||||
- gpio-bank : Specifies which bank a controller owns.
|
||||
- st,supports-sleepmode : Specifies whether controller can sleep or not
|
||||
|
||||
Example:
|
||||
|
||||
gpio1: gpio@8012e080 {
|
||||
compatible = "st,nomadik-gpio";
|
||||
reg = <0x8012e080 0x80>;
|
||||
interrupts = <0 120 0x4>;
|
||||
#gpio-cells = <2>;
|
||||
gpio-controller;
|
||||
interrupt-controller;
|
||||
st,supports-sleepmode;
|
||||
gpio-bank = <1>;
|
||||
};
