scsi: ufs: exynos: Fix DMA alignment for PAGE_SIZE != 4096

2023-03-10T08:28:31+00:00

[ Upstream commit 86bd0c4a2a5dc4265884648cb92c681646509692 ] The Exynos UFS controller only supports scatter/gather list elements that are aligned on a 4 KiB boundary. Fix DMA alignment in case PAGE_SIZE != 4096. Rename UFSHCD_QUIRK_ALIGN_SG_WITH_PAGE_SIZE into UFSHCD_QUIRK_4KB_DMA_ALIGNMENT.

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.
