From: Chris Morgan <macromorgan@hotmail.com>
Add support for the SG Micro SGM41542 charger/boost converter.
Driver was adapted from Rockchip BSP driver [1] and confirmed
with vendor datasheet [2].

From: Chris Morgan <macromorgan@hotmail.com>
Add device tree for the Anbernic RG Vita-Pro, based on the Rockchip
RK3576. All hardware is currently working except for the accelerometer,
the touchscreen, the battery monitor, and DisplayPort over USB-C. PWM
is also missing currently, and as a result the LEDs and panel backlight
are currently controlled via GPIO but will be changed to PWM once
supported.
The Anbernic RG Vita-Pro includes the following hardware:
- A 1080x1920 DSI display with touch.
- 21 buttons.
- 3 LEDs.
- 64GB eMMC, 2 SDMMC slots.
- RTL8852BE WiFi (with Bluetooth via UART)
- 1 USB 3.0 USB-C port in OTG mode.
- 3.5mm headphone jack with play button support.
- 5000mAH battery
The following hardware has incomplete driver support and is not yet
working:
- An Invensense icm42607p accelerometer.
- A Cellwise cw221x battery monitor.
- A Synaptics i2c touchscreen.
- DisplayPort over USB-C alt-mode.
- PWM controller.
- 2 Analog joysticks with LED controllers.
