Add support for IQ-8275-evk board

[PATCH 0/2] Add support for IQ-8275-evk board

Posted by Umang Chheda 3 months, 2 weeks ago

This series:

Add support for Qualcomm's IQ-8275-evk board using QCS8275 SOC.

QCS8275 is another SoC under IQ8 series of SoCs. Unlike QCS8300
which has safety features, it doesn't have safety features which
affects thermal management.

IQ8 EVK board is a single board computer (SBC) that supports various
industrial applications, including factory automation, industrial
robots, drones, edge AI boxes, machine vision, autonomous mobile
robots (AMRs), and industrial gateways.

Below are detailed informations on IQ-8275-evk HW:
------------------------------------------------------
QCS8275 SOM is stacked on top of IQ-8275-evk board.
On top of IQ-8275-evk board additional mezzanine boards can be stacked
in future.
IQ-8275-evk is single board supporting these peripherals:
  - Storage: 1 × 128 GB UFS, micro-SD card, EEPROMs for MACs,
    eMMC on mezzanine card
  - Audio/Video, Camera & Display ports
  - Connectivity: RJ45 2.5GbE, WLAN/Bluetooth, CAN/CAN-FD
  - PCIe ports
  - USB & UART ports

Currently basic features like DSPs, UFS and 'boot to shell' via
uart console are enabled.

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

Yes, I failed to filter that out.

This is just a before and after run with filtering out everything in 
before. I suspect that sometimes warning lines get interleaved and these 
show up as new.

If QCom was warning free, then this would be less of an issue. :(

We're trying.. not always doing the best, but it's on the agenda!

No, it is a correct report. Schema does not allow port and needs to be
fixed.

What's more, this would be pointed out if contributor checked their DTS,
so obviously this never happened.

Internal guideline already asks for it, we asked for it, so why this
keeps happening?

Best regards,
Krzysztof

What I'm saying is, look at the diffstat that I purposefully kept above
- unless modifying qcom.yaml retriggered it (but not any other errors?)

Yes, you are right.
