[PATCH v3 5/6] ufs: host: ufs-exynos: add mphy apb clock mask

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

 



Bit[3] of HCI_CLKSTOP_CTRL register is for enabling/disabling MPHY APB
clock. Lets add it to CLK_STOP_MASK, so that the same can be controlled
during clock masking/unmasking.
