Hello,

This series adds HS-G4 support to the Qcom UFS driver and PHY driver.
The newer Qcom platforms support configuring the UFS controller and PHY
in dual gears (i.e., controller/PHY can be configured to run in two gear
speeds). This is accomplished by adding two different PHY init sequences
to the PHY driver and the UFS driver requesting the one that's required
based on the platform configuration.

Initially the ufs-qcom driver will use the default gear G2 for enumerating
the UFS device. Afer enumeration, the max gear supported by both the
controller and device would be found out and that will be used thereafter.
But for using the max gear after enumeration, the ufs-qcom driver requires
the UFS device to be reinitialized. For this purpose, a separate quirk has
been introduced in the UFS core along with a callback and those will be used
by the ufs-qcom driver.
The series lgtm. This fails for me to apply though due to other patches
I have picked up.

Can you please rebase the phy patches and send those
