arm64: dts: qcom: qrb2210: add dts for Arduino unoq
Arduino UnoQ is a single-board computer combining Qualcomm Dragonwing™ QRB2210 microprocessor with STMicroelectronics STM32U585 microcontroller. Support to a simply boot to shell environment includes: - UART, I2C, SPI - onboard LEDS - eMMC - WLAN and BT Signed-off-by: Riccardo Mereu <r.mereu@arduino.cc> Reviewed-by: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com> Reviewed-by: Krzysztof Kozlowski <krzk@kernel.org> Link: https://lore.kernel.org/r/20251120155825.121483-7-r.mereu.kernel@arduino.cc Signed-off-by: Bjorn Andersson <andersson@kernel.org>master
