Subject: [PATCH v2 1/2] ARM: dts: exynos: Switch to dedicated Odroid-XU3
 sound card binding

The new sound card DT binding is used for Odroid XU3 in order
to properly support the HDMI audio path.
Clocks configuration is changed so the I2S controller is now the bit
and the frame clock master with EPLL as the root clock source.
