Subject: [PATCH v2 0/5] arm64: dts: qcom: sdm845: Add UFS DT nodes

This series updates the device tree bindings for the QMP PHY to
properly specify the registers for dual-lane PHYs. It then updates
the driver to use those new registers. Then it adds the DT nodes for
UFS on SDM845, and activates them on the MTP platform. Finally, it
fixes up the USB3 PHY on SDM845, which is also a dual lane PHY.

The DT binding change is needed because it was discovered that the UFS PHY
driver was reaching beyond its register region, which only happened to work by
virtue of the page size granularity.

Changes since v1:
 - Added dt bindings change, corresponding driver fixup, and USB PHY fixup
 - Renamed ufsphy to phy (Vivek).
 - Removed #clock-cells (Vivek).

This applies atop linux-next 20181018 with the addition of Doug's
changes [1] and [2].
