Radxa Dragon Q6A (https://docs.radxa.com/en/dragon/q6a) is a single board
computer, based on the Qualcomm QCS6490 platform.
The board ships with a modified version of the Qualcomm Linux boot
firmware, which is stored on the onboard SPI NOR flash. This allows
booting standard EFI-based bootloaders from SD/eMMC/USB/UFS/NVMe. It
supports replaceable UFS 3.1/eMMC modules for easy user upgrades.
The board schematic is available at [1].
Features enabled and working:
- Configurable I2C/SPI/UART from 40-Pin GPIO
- Three USB-A 2.0 ports
- RTL8111K Ethernet connected to PCIe0
- eMMC module
- SD card
- M.2 M-Key 2230 PCIe 3.0 x2
- Headphone jack
- Onboard thermal sensors
- QSPI controller for updating boot firmware
- ADSP remoteproc (Type-C and charging features disabled in firmware)
- CDSP remoteproc (for AI applications using QNN)
- Venus video encode and decode accelerator
Features available with additional DT overlays:
- CSI cameras
- DSI display
Features that will be submitted separately once the required bindings are
merged:
- USB-A 3.0 port
- UFS 3.1 module
- HDMI 2.0 port including audio
ALSA UCM and Audioreach topology patches are available at [2] and [3].

My bot found new DTB warnings on the .dts files added or changed in this
series.
Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.
If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:
pip3 install dtschema --upgrade
This patch series was applied (using b4) to base:
Base: using specified base-commit 590b221ed4256fd6c34d3dea77aa5bd6e741bbc1
If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
