Subject: [PATCH v5 00/13] Add MediaTek MT6370 PMIC support
From: ChiaEn Wu <chiaen_wu@...htek.com>
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 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!
Thank you,
ChiaEn Wu
