Because it is using by both ufs-qcom and ufs-hisi and also used in ufs-mediatek in this series, simply re-factor it and then every vendors can reuse it. > > Changes since v5: > - phy-mtk-ufs: Change mphy_readl/mphy_writel() to inline functions. > - Fix typo in cover letter. > > Changes since v4: > - phy-mtk-ufs: > * Sort name in Kconfig and Makefile > * Drop "inline" and fix symbol name for mphy_set_bit()/mphy_clr_bit(). > - dt-bindings: phy-mtk-ufs: Drop "-clk" in clock names. > - dt-bindings: ufs-mediatek: > * Change clock name "ufs-clk" to "ufs". > * Drop vcc related first.
