Also, it stores the phase settings into the dw_mmc controller, so the code has to be adapted to implement that. Changes since v2: - Drop rockchip,v2-tuning and use compatible-based detection - Fix coding style Changes since v1: - Renamed use-v2-tuning to v2-tuning - Rewrite v2-tuning description as the hardware feature Detlev.
