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

[Xilin Wu]

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.

So the RFC is because it cannot be yet merged? Please always add such
note in the cover letter.

Also, are you sure these are real dependencies? Like REALLY real
dependencies?

If there is going to be new version, then codec before cpu (o < p, order

Ah, here it is. That's the most important information, so should be
placed at the top. You do not put the most important information hidden
somewhere in the mail.


Question about dependencies stays, though...

Well, I think these are indeed dependencies. The dtb does build without 
them, but dtbs_check will fail. The board will also malfunction or 
simple crash on boot without the DT and driver changes.

You have a number of features that depend on several other series, and
as Krzysztof pointed out this is difficult to merge/review.. Could you
please create a "linux-next/master-ready" version of this series and
separate the changes for which the dependencies are unmet, putting them
at the end? This way we can take at least some of your diff.

If you still want review on them, you can also send them as [PATCH DNM]
or so

Thanks for the suggestion. I think I can separate the changes that have 
unmet dependencies, and mark them as DNM. Can I send the new series now, 
or am I supposed to wait for a few days?

Xilin,

The prerequisite for the "USB-A 3.0 port (depends on [2])" feature has 
been added - 
https://github.com/torvalds/linux/commit/f842daf740114a8783be566219db34c6a0f1d02c

Could you please check and resend the USB 3.0 port feature?

Thanks.

Best regards,
Andriy
