arm64: dts: mediatek: Regulator cleanup for Chromebooks

[Chen-Yu Tsai <wenst@chromium.org>]

Hi,

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/20260320072302.2402489-1-wenst@chromium.org/
MT6359
- https://lore.kernel.org/all/20260320072440.2403318-1-wenst@chromium.org/
cros-ec-regulator
- https://lore.kernel.org/all/20260320083135.2455444-1-wenst@chromium.org/

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 drops the bogus regulators from the mt6359 dtsi file.

Patch 2 adds a label for the mt6359 regulator sub-node. This is used in
subsequent patches.

Patch 3, 9, and 12 add supplies for the MT6359 PMIC in various
Chromebook designs.

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

Patch 5 adds supplies for the ChromeOS EC controlled regulators in the
Asurada design.

Patch 6 and 13 add power supplies for the CPU cores.

Patch 7 adds the power supply for the SPI NOR flash chip in the Asurada
design.

Patch 8 and 11 fix up load switch descriptions.

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
