[PATCH v2 00/16] arm64: dts: mediatek: Regulator cleanup for Chromebooks

Hi,

This is v2 of my MediaTek Chromebook regulator cleanup series.

Changes since v1:
- Switch to properly named vcn33_[12] regulator nodes for MT6359, and
converted existing users
- Moved PMIC regulator supply properties to PMIC top-level node
- Dropped "mt6359: Add label for regulator sub-node"
- Added all supplies for MT6315, even for unused regulator outputs
- Added missing peripheral supplies on MT8195 Cherry
- Added missing supplies for ChromeOS EC regulators on MT8195 Cherry
- Fixed pp_4200_g regulator name
- Link to v1:

This series contains the device tree bits for the collection of regulator
related cleanups for MediaTek Chromebooks. The device tree binding and
driver changes are:

MT6315
- https://lore.kernel.org/all/20260324053030.4077453-1-wenst@chromium.org/
(merged)
MT6359
- https://lore.kernel.org/all/20260429074113.3720271-1-wenst@chromium.org/
cros-ec-regulator
- https://lore.kernel.org/all/20260320083135.2455444-1-wenst@chromium.org/
(merged)

The goal is to complete the regulator tree so that there are no orphan
regulators, and there are no devices that are missing supplies.

Patch 1, 4 and 10 add supplies for the MT6315 PMIC in various Chromebook
designs.

Patch 2 converts the vcn33_[12]_(wifi|bt) regulator nodes to vcn33_[12].

Patch 3, 9, and 15 add supplies for the MT6359 PMIC in various
Chromebook designs.

Patch 5 and 11 add supplies for the ChromeOS EC controlled regulators.

Patch 6 and 16 add power supplies for the CPU cores.

Patch 7 and 13 add power supplies for the SPI NOR flash chips.

Patch 8 and 12 fix up load switch descriptions.

Patch 14 adds missing supplies for the USB controllers on the Cherry
design.

Obviously the 3 dependency series need to be merged before this series,
or we will get a bunch of new DT validation errors.

Please have a look.

Thanks
ChenYu
