Subject: [PATCH RFC 0/2] arm64: dts: qcom: qcs6490: Introduce Radxa Dragon
 Q6A

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:

- USB-A 3.0 port (depends on [2])
- Three USB-A 2.0 ports
- RTL8111K Ethernet connected to PCIe0
- UFS 3.1 module (depends on [3])
- eMMC module
- SD card
- M.2 M-Key 2230 PCIe 3.0 x2
- HDMI 2.0 port including audio (depends on [2])
- Configurable I2C/SPI/UART from 40-Pin GPIO (depends on [4])
- 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

ALSA UCM and Audioreach topology patches are available at [5] and [6].

This series is posted as an RFC because it depends on several other patch series.
