-WM8903 audio CODEC
-
-This device supports I2C only.
-
-Required properties:
-
- - compatible : "wlf,wm8903"
-
- - reg : the I2C address of the device.
-
- - gpio-controller : Indicates this device is a GPIO controller.
-
- - #gpio-cells : Should be two. The first cell is the pin number and the
- second cell is used to specify optional parameters (currently unused).
-
-Optional properties:
-
- - interrupts : The interrupt line the codec is connected to.
-
- - micdet-cfg : Default register value for R6 (Mic Bias). If absent, the
- default is 0.
-
- - micdet-delay : The debounce delay for microphone detection in mS. If
- absent, the default is 100.
-
- - gpio-cfg : A list of GPIO configuration register values. The list must
- be 5 entries long. If absent, no configuration of these registers is
- performed. If any entry has the value 0xffffffff, that GPIO's
- configuration will not be modified.
-
- - AVDD-supply : Analog power supply regulator on the AVDD pin.
-
- - CPVDD-supply : Charge pump supply regulator on the CPVDD pin.
-
- - DBVDD-supply : Digital buffer supply regulator for the DBVDD pin.
-
- - DCVDD-supply : Digital core supply regulator for the DCVDD pin.
