Subject: ARM: dts: Add sound node for exynos5250-snow board
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=80f78ad8af2171a852e3737908f527692d52f51c;p=linux-beck.git

ARM: dts: Add sound node for exynos5250-snow board

The audio codec on Snow board, MAX98095 is connected on I2C7 bus.
Also it requires the GPX1-7 line to be pulled up.

Updated Snow DTS file to incorporate above changes and added a
sound node to instantiate the I2S-based sound card.
