[PATCH v3 00/14] Add Mediatek MT6370 PMIC support

[ChiaEn Wu <peterwu.pub@gmail.com>]

From: ChiaEn Wu <chiaen_wu@richtek.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.

Among with this we took some changes and refined the device tree files to
comply with DT specifications.

Thank you,
ChiaEn Wu

Changes in v2:
- In patch 01/15:
	- Add "unevaluatedProperties: false".
