Changes since v2: - Fixed vsys-smps-supply property name (from "vspms-supply") - Collected reviewed-by on patch 3 - Included Lee in recipients (sorry about that) - Link to v2: https://lore.kernel.org/all/20260429074113.3720271-1-wenst@chromium.org/ Changes since v1: - Moved regulator supply properties up to the PMIC mfd node - This requires moving the properties to the mfd bindings - deprecated vcn33_[12]_(bt|wifi) regulators and added vcn33_[12] - model the deprecated ones as downstream to the new ones (vcn33_[12] -> vcn33_[12]_(bt|wifi) - Handle internal supply of vbbck directly in the driver, instead of specifying it in the binding - Added patch to constify data structures in the regulator driver - Link to v1: https://lore.kernel.org/all/20260320072440.2403318-1-wenst@chromium.org/ This series is part of a broader collection of regulator related cleanups for MediaTek Chromebooks. This one covers the MT6359 PMIC. The MT6359 PMIC is similar to the MT6358 and MT6366 PMICs. I've done cleanups for those in the past. Patch 1 adds the names of the power supply inputs to the binding. Patch 2 drops the restrictions on the regulator-name property from the binding. The name of the supply rail ideally should match the design schematics, not the PMIC's output name. The DT should be free to set whatever name it needs. Patch 3 deprecates the vcn33_[12]_(bt|wifi) regulators, and adds new proper vcn33_[12] regulators. The two *real* VCN33 regulator outputs each have two enable bits that are OR-ed together to control the output. This allowed WiFi and BT stacks to separately control power output without coordination. Patch 4 constifies the data structures used throughout the regulator driver. While not directly related, it touches the same context and it is easier to include it in the series. Patch 5 adds the supply names from the DT binding change in patch 2 to the regulator descriptions in the driver. This patch has a whole bunch of checkpatch.pl warnings, but I wonder if it's because the context size for checking complex macros is not large enough. Patch 6 implements the changes of the DT binding change in patch 3. One part not yet covered in this series is the removal of the *_sshub regulators. These are not actual regulators, but a set of separate configurations to be used by the low power sensor hub or embedded controller. How these combine with the standard set of configurations set by the main processor is TBD. Device tree changes will be sent separately. The goal is to get the regulator tree as complete as possible. This includes adding supply names to other regulator DT bindings, and adding all the supply links to the existing DTs. Please have a look.
