[PATCH 2/2] mmc: dw_mmc-pltm: Remove Rockchip's custom dw_mmc driver structure

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Dinh Nguyen <dinguyen@xxxxxxxxxx>

Rockchip's implementation of the dw_mmc controller only requires the setting
of the SDMMC_CMD_USE_HOLD_REG on every command. With the patch to set the
SDMMC_CMD_USE_HOLD_REG by checking the slot's speed mode, this Rockchip
custom driver structure is no longer necessary.
