-Freescale Digital Audio Mux (AUDMUX) device
-
-Required properties:
-
- - compatible : "fsl,imx21-audmux" for AUDMUX version firstly used
- on i.MX21, or "fsl,imx31-audmux" for the version
- firstly used on i.MX31.
-
- - reg : Should contain AUDMUX registers location and length.
-
-An initial configuration can be setup using child nodes.
-
-Required properties of optional child nodes:
-
- - fsl,audmux-port : Integer of the audmux port that is configured by this
- child node.
-
- - fsl,port-config : List of configuration options for the specific port.
- For imx31-audmux and above, it is a list of tuples
- <ptcr pdcr>. For imx21-audmux it is a list of pcr
- values.
-
-Example:
-
-audmux@21d8000 {
- compatible = "fsl,imx6q-audmux", "fsl,imx31-audmux";
- reg = <0x021d8000 0x4000>;
-};
