-Samsung Exynos5433 TM2(E) audio complex with WM5110 codec
-
-Required properties:
-
- - compatible : "samsung,tm2-audio"
- - model : the user-visible name of this sound complex
- - audio-codec : the first entry should be phandle of the wm5110 audio
- codec node, as described in ../mfd/arizona.txt;
- the second entry should be phandle of the HDMI
- transmitter node
- - i2s-controller : the list of phandle and argument tuples pointing to
- I2S controllers, the first entry should be I2S0 and
- the second one I2S1
- - audio-amplifier : the phandle of the MAX98504 amplifier
- - samsung,audio-routing : a list of the connections between audio components;
- each entry is a pair of strings, the first being the
- connection's sink, the second being the connection's
- source; valid names for sources and sinks are the
- WM5110's and MAX98504's pins and the jacks on the
- board: HP, SPK, Main Mic, Sub Mic, Third Mic,
- Headset Mic
- - mic-bias-gpios : GPIO pin that enables the Main Mic bias regulator
-
-
-Example:
-
-sound {
- compatible = "samsung,tm2-audio";
- audio-codec = <&wm5110>, <&hdmi>;
- i2s-controller = <&i2s0 0>, <&i2s1 0>;
- audio-amplifier = <&max98504>;
- mic-bias-gpios = <&gpr3 2 0>;
- model = "wm5110";
