Subject: [PATCH 3/3] arm64: dts: qcom: msm8916-zhihe: Add initial device tree for zhihe Wifi/LTE dongle UFI-001C and uf896
This commit adds support for the ufi-001C and uf896 WiFi/LTE dongle made by
unknown manufactures based on MSM8916.
uf896 is another variant for the zhihe usb stick. The board design
difers by using different gpios for the keys and leds.
Note: The original firmware does not support 64-bit OS. It is necessary
to flash 64-bit TZ firmware to boot arm64.
Currently supported:
- All CPU cores
- Buttons
- LEDs
- Modem
- SDHC
- USB Device Mode
- UART
