mmc_sd_init_uhs_card function sets the driver type, current limit and bus speed mode on card as well as on host controller side. Currently bus speed mode is set by sending CMD6 to card and immediately setting the timing mode in host controller. But then before initiating tuning sequence, it also tries to set current limit by sending CMD6 to card which results in data timeout errors in controller if bus speed mode is SDR50/SDR104 mode. So basically bus speed mode should be set only after current limit is set in the card and immediately after setting the bus speed mode, tuning sequence should be initiated.
