Patch 1 is the dt-bindings. Patch 2-4 deal with rpm and spm support in advanced suggested by Ulf. Patch 5 exports two new APIs for host driver. Patch 6 and 7 are the host driver and dtsi support. Changes in v5: - use ufshc for devicetree example - fix a compile warning - use device_set_awake_path() and disable ref_out_clk in suspend - remove pd_id from header - recontruct ufs_rockchip_hce_enable_notify() to workaround hce enable without using new quirk Changes in v4: - properly describe reset-gpios - deal with power domain of rpm and spm suggested by Ulf - Fix typo and disable clks in ufs_rockchip_remove - remove clk_disable_unprepare(host->ref_out_clk) from ufs_rockchip_remove Changes in v3: - rename the file to rockchip,rk3576-ufshc.yaml - add description for reset-gpios - use rockchip,rk3576-ufshc as compatible - reword Kconfig description - elaborate more about controller in commit msg - use rockchip,rk3576-ufshc for compatible - remove useless header file - remove inline for ufshcd_is_device_present - use usleep_range instead - remove initialization, reverse Xmas order - remove useless varibles - check vops for null - other small fixes for err path - remove pm_runtime_set_active - fix the active and inactive reset-gpios logic - fix rpm_lvl and spm_lvl to 5 and move to end of probe path - remove unnecessary system PM callbacks - use UFSHCI_QUIRK_DME_RESET_ENABLE_AFTER_HCE instead of UFSHCI_QUIRK_BROKEN_HCE Changes in v2: - rename the file - add reset-gpios Shawn Lin (6): dt-bindings: ufs: Document Rockchip UFS host controller soc: rockchip: add header for suspend mode SIP interface pmdomain: rockchip: Add smc call to inform firmware scsi: ufs: core: Export ufshcd_dme_reset() and ufshcd_dme_enable() scsi: ufs: rockchip: initial support for UFS arm64: dts: rockchip: Add UFS support for RK3576 SoC Ulf Hansson (1): pmdomain: core: Introduce dev_pm_genpd_rpm_always_on() .../bindings/ufs/rockchip,rk3576-ufshc.yaml | 105 ++++++ arch/arm64/boot/dts/rockchip/rk3576.dtsi | 25 ++ drivers/pmdomain/core.c | 34 ++ drivers/pmdomain/rockchip/pm-domains.c | 8 + drivers/ufs/core/ufshcd.c | 6 +- drivers/ufs/host/Kconfig | 12 + drivers/ufs/host/Makefile | 1 + drivers/ufs/host/ufs-rockchip.c | 368 +++++++++++++++++++++ drivers/ufs/host/ufs-rockchip.h | 48 +++ include/linux/pm_domain.h | 7 + include/soc/rockchip/rockchip_sip.h | 3 + include/ufs/ufshcd.h | 2 + 12 files changed, 617 insertions(+), 2 deletions(-) create mode 100644 Documentation/devicetree/bindings/ufs/rockchip,rk3576-ufshc.yaml create mode 100644 drivers/ufs/host/ufs-rockchip.c create mode 100644 drivers/ufs/host/ufs-rockchip.h Reviewed-by: Manivannan Sadhasivam
