Patch 1 adds new quirk and patch 2 is the dt-bindings. Patch 3-6 deal with rpm and spm support in advanced suggested by Ulf. Final patch 5 is the driver added. 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): scsi: ufs: core: Add UFSHCI_QUIRK_DME_RESET_ENABLE_AFTER_HCE 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 PM: wakeup: Add device_clr_wakeup_path() scsi: ufs: rockchip: initial support for UFS Ulf Hansson (1): pmdomain: core: Introduce dev_pm_genpd_rpm_always_on() .../bindings/ufs/rockchip,rk3576-ufshc.yaml | 105 +++++++ drivers/pmdomain/core.c | 34 +++ drivers/pmdomain/rockchip/pm-domains.c | 7 + drivers/ufs/core/ufshcd.c | 17 ++ drivers/ufs/host/Kconfig | 12 + drivers/ufs/host/Makefile | 1 + drivers/ufs/host/ufs-rockchip.c | 340 +++++++++++++++++++++ drivers/ufs/host/ufs-rockchip.h | 51 ++++ include/linux/pm_domain.h | 7 + include/linux/pm_wakeup.h | 7 + include/soc/rockchip/rockchip_sip.h | 3 + include/ufs/ufshcd.h | 6 + 12 files changed, 590 insertions(+) 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
