This patch series add MediaTek MT6370 LED indicator and flashlight 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.
First, in this series of patches,
- 'dt-binding: mfd' and 'mfd driver' have been applied by Lee in v7.
