- reset-names : Must include the following entries: "acodec-reset".
Optional properties:
- rockchip,adc-grps: This is a variable length array, that shows the mapping of
the configuration adc grp. The following shows the relationship between grp
- rockchip,enable-all-adcs: This is a boolean type property, that shows whether
force enable all of ADCs. The following shows the relationship between grps
and ADC:
* grp 0 -- select ADC1 / ADC2
* grp 1 -- select ADC3 / ADC4
* grp 2 -- select ADC5 / ADC6
* grp 3 -- select ADC7 / ADC8
By default, they are all enabled, like using:
- rockchip,adc-grps = <0 1 2 3>;
If we don't use ADC5 and ADC6, we just use grp 0,1,3 on dts. For example:
- rockchip,adc-grps = <0 1 3>;
If the property is not used, the enabled ADC groups refer to needed channels
via configure hw_params.
- rockchip,adc-grps-route: This is a variable length array, that shows the
mapping route of ACODEC sdo to I2S sdi. By default, they are one-to-one
