    Subject[PATCH v2 07/12] ARM: dts: rockchip: enable the high speed on sdio for kylin board
    Date
    We want to the higher speed for wifi module working.

    Bootup kernel log:
    ...
    mmc_host mmc0: Bus speed (slot 0) = 37125000Hz (slot req 37500000Hz,
    actual 37125000HZ div = 0)

    or run 'cat /sys/kernel/debug/clk/clk_summary |grep phase -C 1' to check
    Otherwise, the mmc0 will run 400khz defalult value to work.
