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.
