+Required properties:
- compatible : "samsung,tm2-audio"
SoC specific compatible string please.
- samsung,model : the user-visible name of this sound complex
I think we have a standard property for this.
- clocks : must contain an entry for each entry in clock-names,
- see ../clocks/clock-bindings.txt for details
- clock-names : must include the following entries:
- "mclk1", "mclk2"
- samsung,i2s-controller : the phandle of the I2S controller
- samsung,speaker-amplifier : the phandle of the MAX98504 amplifier
We should have standard properties for these. 2nd ones I've seen today.
- 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";
- clocks = <&pmu_system_controller 0>, <&s2mps13_osc 2>;
- clock-names = "mclk1", "mclk2";
- samsung,i2s-controller = <&i2s0>;
- samsung,speaker-amplifier = <&max98504>;
- samsung,model = "wm5110";
- mic-bias-gpios = <&gpr3 2 0>;
- samsung,audio-routing =
"HP", "HPOUT1L","HP", "HPOUT1R","SPK", "SPKOUT","SPKOUT", "HPOUT2L","SPKOUT", "HPOUT2R","Main Mic", "MICBIAS2","IN1R", "Main Mic";+};
