From: Chris Morgan <macromorgan@xxxxxxxxxxx>
Add support for the GameForce Chi, which is a handheld gaming console
from GameForce with a Rockchip RK3326 SoC. The device has a 640x480
3.5" dual-lane DSI display, one analog joystick connected to the SoC
SARADC controller and a second analog joystick connected to an unknown
UART based ADC, a single SD card slot, a single USB-C port for
charging, and onboard RTL8723BS WiFi/Bluetooth combo, multiple face
buttons, and an array of R/G/B LEDs used for key backlighting.
The vendor was unable to provide details on the unknown UART based
ADC which I have documented via a comment in the device-tree, and
the vendor also does not have available Bluetooth firmware (the BT
was not previously working on the vendor's OS, this has also been
noted in a device-tree comment).
Aside from the right analog ADC joystick and bluetooth all hardware has
been tested and is working as expected.
