Subject: ARM: dts: rockchip: Set sdmmc frequency at boot time for rk3066a
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=04a6e5e83a37cdcc45bf53970b03f6a8e58e3462;p=linux.git

ARM: dts: rockchip: Set sdmmc frequency at boot time for rk3066a

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