Hello Stanislav.
Use memory-region instead of reg property pointing to framebuffer.
Happy to see the phone progressing towards mainline support!

Hello David,
Thank you for the review. I will fix it in v2.
Best regards,

What does that mean? CVP is strongly connected with the video
hardware, but they're not quite the same

= <2> would be neater
If you have an easy way of modifying the (presumably) downstream-based
image which you use for ramoops, you may want to add ecc-size = <8>
too, so that it's more robust

Any chance you know what they're used for? (you can often correlate them
with QUP pinctrl entries, as they're often fingerprint scanner/NFC eSE
connections)
If you do, please sprinkle in some comments, like in x1-crd.dtsi

Did you check whether that's the case with a ""real"" USB3 Type-C
cable? Does a Type-C dongle with a HDMI/DP output work if you plug it
in when running downstream?
