Subject: [PATCH] ARM64: rk3368: add tuning clk for emmc and sdmmc
Date: Mon, 25 Jan 2016 15:33:43 +0800 [thread overview]
Message-ID: <1453707223-28855-1-git-send-email-shawn.lin@rock-chips.com> (raw)
Add tuning clk for emmc and sdmmc, otherwise I get
the following failure while enabling mmc-hs200-1_8v.
dwmmc_rockchip ff0f0000.dwmmc: Tuning clock (sample_clk) not defined.
mmc0: tuning execution failed
mmc0: error -5 whilst initialising MMC card
With it
dwmmc_rockchip ff0f0000.dwmmc: Successfully tuned phase to 170
mmc0: new HS200 MMC card at address 0001
mmcblk0: mmc0:0001 M8G1GC 7.28 GiB
