| 5 | Required properties: | |
| 6 | ||
| 7 | - compatible : "qcom,apq8016-sbc-sndcard" | |
| 8 | ||
| 9 | - pinctrl-N : One property must exist for each entry in | |
| 10 | pinctrl-names. See ../pinctrl/pinctrl-bindings.txt | |
| 11 | for details of the property values. | |
| 12 | - pinctrl-names : Must contain a "default" entry. | |
| 13 | - reg : Must contain an address for each entry in reg-names. | |
| 14 | - reg-names : A list which must include the following entries: | |
| 15 | * "mic-iomux" | |
| 16 | * "spkr-iomux" | |
