Gateworks PLD GPIO controller bindings |
|
|
|
The GPIO controller should be a child node on an I2C bus, |
|
see: i2c/i2c.txt for details. |
|
|
|
Required properties: |
|
- compatible: Should be "gateworks,pld-gpio" |
|
- reg: I2C slave address |
|
- gpio-controller: Marks the device node as a GPIO controller. |
|
- #gpio-cells: Should be <2>. The first cell is the gpio number and |
|
the second cell is used to specify optional parameters. |
|
|
|
Example: |
|
|
|
pld@56 { |
|
compatible = "gateworks,pld-gpio"; |
|
reg = <0x56>; |
|
gpio-controller; |
|
#gpio-cells = <2>; |
|
};
