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 phandle of the wm5110 audio codec node,
as described in ../mfd/arizona.txt
- i2s-controller : the phandle of the I2S controller
- 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>;
i2s-controller = <&i2s0>;
audio-amplifier = <&max98504>;
mic-bias-gpios = <&gpr3 2 0>;
model = "wm5110";
samsung,audio-routing =
"HP", "HPOUT1L",
"HP", "HPOUT1R",
"SPK", "SPKOUT",
"SPKOUT", "HPOUT2L",
"SPKOUT", "HPOUT2R",
"Main Mic", "MICBIAS2",
"IN1R", "Main Mic";
