> The SD clock disable is wrapped by MMC_SUPPORTS_TUNING. So it
> only works when UHS is enabled. However, in SD initialization the

> disable the SD clock before power down.
> So this causes a problem when UHS is not enabled. Some cards can't
> become ready (ACMD14 timeout) due to the clock is enabled during
> power cycle.
