ufs: snapshot of UFS controller & PHY driver
This is a snapshot of UFS driver (host controller and PHY) taken as of
msm-4.4 commit <98b0bcfa> ("wil6210: fix memory access violation in
wil_memcpy_from/toio_32").
Snapshot is taken of following files:
drivers/scsi/ufs/*
drivers/phy/phy-qcom-ufs*
drivers/phy/Makefile
include/linux/phy/phy-qcom-ufs.h
include/uapi/scsi/ufs/*
include/trace/events/ufs.h
Documentation/scsi/ufs.txt
Documentation/devicetree/bindings/ufs/*
Fixed some of the minor compilation errrors after taking the snapshot.
