Hi,
This patch series provides some features and fixes in MediaTek UFS platforms,
1. Support VA09 regulator operations
2. Support option to disable auto-hibern8
3. Support HS-G4
4. Decouple features from platform bindings
5. Misc fixes

In ufs_mtk_unipro_set_lpm(), use specific unsigned values
as the argument to invoke ufshcd_dme_set().
In the same time, change the name of ufs_mtk_unipro_set_pm()
to ufs_mtk_unipro_set_lpm() to align the naming convention
in MediaTek UFS driver.

This change is the echo of your suggestion in
https://patchwork.kernel.org/project/linux-scsi/patch/20200908064507.30774-4-stanley.chu@mediatek.com/
Actually I think your suggestion is constructive that the accepted
values of VS_UNIPROPOWERDOWNCONTROL are better clearly defined so I use
the casting here in this patch.

Some MediaTek UFS platforms need to control VA09 power
specifically. Provide such control according to the device
tree binding.

UFS proprietary features (including features introduced later) in
MediaTek UFS platforms have complicated combinations among different
platforms.
To ease code readability and maintenance, decouple all proprietary
features from platform bindings. Each feature would be enabled only
if specific property string is defined in device tree node.

UFS proprietary features (including features introduced later) in
MediaTek UFS platforms have complicated combinations among different
platforms.
To ease code readability and maintenance, decouple all proprietary
features from platform bindings. Each feature would be enabled only
if specific property string is defined in device tree node.

Support an option to allow users to disable auto-hibern8 feature.
Instead, enable hibern8-during-clk-gating feature to keep similar
power consumption.

Some vendors need newer UniPro version to decide if some features
can be enabled or not.
Simply add missing enums for the latest UniPro versions.

Some vendors need newer UniPro version to decide if some features
can be enabled or not.
Simply add missing enums for the latest UniPro versions.

Provide HS-G4 support in MediaTek UFS platforms.
To support HS-G4, introduce mechanism to get the
MediaTek UFS controller version. With such information,
driver can make right decision to apply different
configurations in different controllers.
