Subject: [PATCH v2 0/5] exynos-ufs: Add support for UFS HCI

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