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 used to adjust the Makefile order. (https://lore.kernel.org/all/20220616182524.7956-2-andriy.shevchenko@linux.intel.com/) Among with this, we took some changes for MT6370 and refined the MT6370 device tree files to comply with DT specifications. "[PATCH v5 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!
