|
|
|
|
Required properties:
|
|
|
|
- compatible : "qcom,apq8016-sbc-sndcard"
|
|
|
|
- pinctrl-N : One property must exist for each entry in
|
|
pinctrl-names. See ../pinctrl/pinctrl-bindings.txt
|
|
for details of the property values.
|
|
- pinctrl-names : Must contain a "default" entry.
|
|
- reg : Must contain an address for each entry in reg-names.
|
|
