[alsa-devel] [PATCH] ARM: dts: Support audio on Exynos5422-odroidxu3 using simple-audio-card

[Inha Song]

Add MAX98090 audio codec, I2S interface and the sound nodes to support
audio on Exynos5422 SoC Based Odroid-XU3 board. Now we can support audio
in Odroid-XU3 board using simple-audio-card DT binding.
