+
+For Rockchip platform, DLL bypass bit and start bit need to be set if
+DLL is not locked. And adjust pre-change delay to 0x3 for better signal
+test result.

+Subject: [PATCH] mmc: sdhci-of-dwcmshc: properly determine max clock on
+ Rockchip
+
+Currently .get_max_clock returns the current clock rate for cclk_emmc
+on rk35xx, thus max clock gets set to whatever bootloader set it to.
+
+In case of u-boot, it is intentionally reset to 50 MHz if it boots
+from eMMC, see mmc_deinit() in u-boot sources. As a result, HS200 and
+HS400 modes are never selected by Linux, because dwcmshc_rk35xx_postinit
+clears appropriate caps if host->mmc->f_max is < 52MHz
+
+cclk_emmc is not a fixed clock on rk35xx, so using
+sdhci_pltfm_clk_get_max_clock is not appropriate here.
+
+Implement rk35xx_get_max_clock that returns actual max clock for cclk_emmc.
