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";
-};
