- compatible : Should be "ti,afe4403".
|
||
|
|
- reg : SPI chip select address of device.
|
||
|
|
- tx-supply : Regulator supply to transmitting LEDs.
|
||
|
|
- interrupt-parent : Phandle to he parent interrupt controller.
|
||
|
|
- interrupts : The interrupt line the device ADC_RDY pin is
|
||
|
|
connected to. For details refer to,
|
||
|
|
../../interrupt-controller/interrupts.txt.
