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: https://lore.kernel.org/all/20260320084351.2461060-1-wenst@chromium.org/ 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.
