From: ChiaEn Wu <chiaen_wu@xxxxxxxxxxx> This patch series add MediaTek MT6370 PMIC support. The MT6370 is a highly-integrated smart power management IC, which includes a single cell Li-Ion/Li-Polymer switching battery charger, a USB Type-C & Power Delivery (PD) controller, dual Flash LED current sources, a RGB LED driver, a backlight WLED driver, a display bias driver and a general LDO for portable devices. In this series of patches, we based on Andy Shevchenko's mfd patch which is used to adjust the Makefile order. (https://lore.kernel.org/all/20220801114211.36267-3-andriy.shevchenko@xxxxxxxxxxxxxxx/) Among this, we also took some changes for MT6370 drivers, revised the MT6370 device tree files to comply with DT specifications, and revised the wrong SoB chain in entire patches. PS. "[PATCH v7 06/13] dt-bindings: mfd: Add MediaTek MT6370" depends on previous DT binding patches, so before applying this patch, please apply other DT patches first. Thanks! PS2. Our MFD DT-binding depends on LED flash and LED RGB DT-bindings, but the Kconfigs of LED flash and LED RGB depend on MFD. Due to dependency consideration, we also submit LED flash and LED RGB with other patches at this time.
