Subject: [PATCH] ARM: dts: rockchip: Set sdmmc frequency at boot time for
 rk3066a
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Currently driver leaves sdmmc frequency at its default.
So lets set this to 50MHz.
This gives us performance boost in mmc transfers.
