From: Dinh Nguyen <dingu...@altera.com> Hi,
This is v2 of the patch series that makes the setting of the SDMMC_CMD_USE_HOLD_REG bit generic. v2 differences: * Another part of the spec on dw_mmc states, "Never set CMD.use_hold_reg = 1 and cclk_in_drv phase shift to 0 at the same time. This would add an extra one-cycle delay on the output path, resulting in incorrect behavior." The cclk_in_drv phase shift is the 2nd parameter in the "samsung,dw-mshc-sdr-timing" and "samsung,dw-mshc-ddr-timing" bindings. V2 checks for the cclk_in_drv phase shift value. If cclk_in_drv = 0, then we cannot set the SDMMC_CMD_USE_HOLD_REG bit. * Removes the Exynos' platform specific prepare_command's function that sets the SDMMC_CMD_USE_HOLD_REG based on the cclk_in_drv phase shift value.
