ASoC: samsung: Remove unused Odroid x2/u3 machine driver
We have been using "simple-audio-card" for Odroid X2/U3 boards, as can be seen from sound node in arch/arm/boot/dts/ exynos4412-odroid-common.dtsi. A dedicated machine driver is not needed and it is removed in this patch. There is no dts files using "samsung,odroidx2-audio" or "samsung,odroidu3-audio" compatible strings.

Samsung Exynos Odroid X2/U3 audio complex with MAX98090 codec
|
||||
|
||||
Required properties:
|
||||
- compatible : "samsung,odroidx2-audio" - for Odroid X2 board,
|
||||
"samsung,odroidu3-audio" - for Odroid U3 board
|
||||
- samsung,model : the user-visible name of this sound complex
|
||||
- samsung,i2s-controller : the phandle of the I2S controller
|
||||
- samsung,audio-codec : the phandle of the MAX98090 audio codec
|
||||
- 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 MAX98090's pins (as
|
||||
documented in its binding), and the jacks on the board
|
||||
For Odroid X2:
|
||||
* Headphone Jack
|
||||
* Mic Jack
|
||||
* DMIC
|
||||
|
||||
For Odroid U3:
|
||||
* Headphone Jack
|
||||
* Speakers
|
||||
|
||||
Example:
|
||||
|
||||
sound {
|
||||
compatible = "samsung,odroidu3-audio";
|
||||
samsung,i2s-controller = <&i2s0>;
|
||||
samsung,audio-codec = <&max98090>;
|
||||
samsung,model = "Odroid-X2";
|
||||
samsung,audio-routing =
|
||||
"Headphone Jack", "HPL",
|
||||
"Headphone Jack", "HPR",
|
||||
"IN1", "Mic Jack",
|
||||
"Mic Jack", "MICBIAS";
