I could not find the datasheet myself on the Internet, I found other
datasheets of other panels from the same vendor though.

I confirm I am talking about the R2 package (not B2 your find).

Yes there are min/typ/max timings in the datasheet, I didn't know about
display_mode (copied/pasted another random timing structure and adapted
it). I will try to adapt.

Any reason to create one (almost empty) file by compatible? As
comparison, simple I2C/SPI devices with no singularities are
listed there:
Documentation/devicetree/bindings/trivial-devices.yaml

I'll create a bindings file for this panel though.

Thanks,
