scsi: ufs: renesas: Fix private allocation

2023-08-16T16:27:30+00:00

commit b6d128f89a85771433a004e8656090ccbe1fb969 upstream. Should use devm_kzalloc() for struct ufs_renesas_priv because the .initialized should be false as default.

scsi: ufs: core: Allow host driver to disable wb toggling during clock scaling

2022-08-23T03:07:50+00:00

Mediatek UFS does not want to toggle write booster during clock scaling. Permit host driver to disable wb toggling during clock scaling. Introduce a flag UFSHCD_CAP_WB_WITH_CLK_SCALING to decouple WB and clock scaling. UFSHCD_CAP_WB_WITH_CLK_SCALING is only valid when UFSHCD_CAP_CLK_SCALING is set. Just like UFSHCD_CAP_HIBERN8_WITH_CLK_GATING is valid only when UFSHCD_CAP_CLK_GATING set. Set UFSHCD_CAP_WB_WITH_CLK_SCALING for qcom to compatible legacy design at the same time.

scsi: ufs: ufs-mediatek: Support clk-scaling to optimize power consumption

2022-08-23T02:58:30+00:00

Provide clk-scaling feature in MediaTek UFS platforms. MediaTek platform supports clk-scaling by switching parent clock mux of UFSHCI main clocks: ufs_sel. The driver needs to prevent changing the rate of ufs_sel because its parent PLL clock may be shared between multiple IPs. In order to achieve this goal, the maximum and minimum clock rates of ufs_sel defined in dts should match the rate of "ufs_sel_max_src" and "ufs_sel_min_src" respectively.
