Industrial I/O subsystem bindings for ADC controller found in |
|
Ingenic JZ47xx SoCs. |
|
|
|
ADC clients must use the format described in |
|
https://github.com/devicetree-org/dt-schema/blob/master/schemas/iio/iio-consumer.yaml, |
|
giving a phandle and IIO specifier pair ("io-channels") to the ADC controller. |
