arm64: dts: qcom: msm8916-thwc: Add initial device trees
This commit adds support for the ufi-001C and uf896 WiFi/LTE dongle made by Tong Heng Wei Chuang based on MSM8916. uf896 is another variant for the usb stick. The board design differs 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 Co-developed-by: Jaime Breva <jbreva@nayarsystems.com> Signed-off-by: Jaime Breva <jbreva@nayarsystems.com> Co-developed-by: Nikita Travkin <nikita@trvn.ru> Signed-off-by: Nikita Travkin <nikita@trvn.ru> Signed-off-by: Yang Xiwen <forbidden405@foxmail.com> Signed-off-by: Bjorn Andersson <andersson@kernel.org>
