This patch is fine with one minor nit which can be done now or I can do it later when I add the R-Car support. > + * Some controllers have a 32-bit wide data port register > + */ > +#define TMIO_MMC_32BIT_DATA_PORT (1 << 9) Since R-Car Gen3 has 64 bit port, I'd suggest to use TMIO_MMC_BIG_DATA_PORT or something. But as I said, I can also do this later. So Reviewed-by: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>
