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. 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-rc2 In past there was couple of attempt to upstream this driver, but it didn't went upstream for some or other reason.
