Required properties:
|
||
|
- compatible: "fsl,vf610-iomuxc"
|
||
|
- fsl,pins: two integers array, represents a group of pins mux and config
|
||
|
setting. The format is fsl,pins = <PIN_FUNC_ID CONFIG>, PIN_FUNC_ID is
|
||
|
a pin working on a specific function, CONFIG is the pad setting value
|
||
|
such as pull-up, speed, ode for this pin. Please refer to Vybrid VF610
|
||
|
datasheet for the valid pad config settings.
