This patch-set introduces UFS (Universal Flash Storage) host controller support for Samsung family SoC. Mostly, it consists of UFS PHY and host specific driver. - Changes since v4: * Addressed review comments from Avir and Rob * Minor improvment on the ufs phy and ufshc drivers * Added Tested-by from Pawel * Change UFS binding to DT schema format - Changes since v3: * Addressed Kishon's and Avir's review comments * fixed make dt_binding_check error as pointed by Rob - Changes since v2: * fixed build warning by kbuild test robot * Added Reported-by tags - Changes since v1: * fixed make dt_binding_check error as pointed by Rob * Addressed Krzysztof's review comments * Added Reviewed-by tags patch 1/5: define devicetree bindings for UFS PHY patch 2/5: Adds UFS PHY driver patch 3/5: define devicetree bindings for UFS HCI patch 4/5: Adds Samsung UFS HCI driver patch 5/5: Enabled UFS on exynos7 platform Note: This series is based on Linux-5.6 (commit: 7111951b8d49) Alim Akhtar (5): dt-bindings: phy: Document Samsung UFS PHY bindings phy: samsung-ufs: add UFS PHY driver for samsung SoC dt-bindings: ufs: Add DT binding documentation for ufs scsi: ufs-exynos: add UFS host support for Exynos SoCs arm64: dts: Add node for ufs exynos7 .../bindings/phy/samsung,ufs-phy.yaml | 74 + .../bindings/ufs/samsung,exynos-ufs.yaml | 93 ++ .../boot/dts/exynos/exynos7-espresso.dts | 4 + arch/arm64/boot/dts/exynos/exynos7.dtsi | 44 +- drivers/phy/samsung/Kconfig | 9 + drivers/phy/samsung/Makefile | 1 + drivers/phy/samsung/phy-exynos7-ufs.h | 85 ++ drivers/phy/samsung/phy-samsung-ufs.c | 369 +++++ drivers/phy/samsung/phy-samsung-ufs.h | 142 ++ drivers/scsi/ufs/Kconfig | 12 + drivers/scsi/ufs/Makefile | 1 + drivers/scsi/ufs/ufs-exynos.c | 1288 +++++++++++++++++ drivers/scsi/ufs/ufs-exynos.h | 284 ++++ drivers/scsi/ufs/unipro.h | 36 + 14 files changed, 2440 insertions(+), 2 deletions(-) create mode 100644 Documentation/devicetree/bindings/phy/samsung,ufs-phy.yaml create mode 100644 Documentation/devicetree/bindings/ufs/samsung,exynos-ufs.yaml create mode 100644 drivers/phy/samsung/phy-exynos7-ufs.h create mode 100644 drivers/phy/samsung/phy-samsung-ufs.c create mode 100644 drivers/phy/samsung/phy-samsung-ufs.h create mode 100644 drivers/scsi/ufs/ufs-exynos.c create mode 100644 drivers/scsi/ufs/ufs-exynos.h base-commit: 7111951b8d4973bda27ff663f2cf18b663d15b48 -- 2.17.1
