Could do, although I think it is used for more than one of the Anbernic 
devices, so "anbernic,wl-355608-a8" might be best. Happy to go with whatever 
approach is preferred.

Hi Ryan,

How about to use "anbernic,rg35xx-panel" ?
It's not generic though, some other drivers use similar strings already.

I was going to go with "wl,wl-355608-a8" as the whole string seems to be the 
product/serial code, but happy to just not have the vendor prefix as per my V1 
if that's acceptable, seems pretty obscure as you've found.

You mean, "wl,355608-a8"? I did a wee bit of googling of the thing, and
yeah, there's nothing that a surface level search turns up for it -
other than they appeared to have a logo with a W in a circle...
I think if we genuinely do not know what the vendor is then we just
don't have a prefix.

Thanks, I don't actually know the vendor, would it be acceptable to just use 
"wl"?

Thanks, changed underscore to dash mid-patch and neglected to fix all the 
examples (and the subsequent code patch it seems. Will correct. Is there a

You're missing a vendor prefix here. And when you add it, update the
filename to match.

All of this is not needed in the example, all you need to have here is:

spi {
#address-cells = <1>;
#size-cells = <0>;

This "panel" label is not used, you should drop it.

This doesn't match what you documented, be sure to run dt_binding_check.

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:
Documentation/devicetree/bindings/display/panel/wl-355608-a8.example.dtb: 
/example-0/spi/panel@0: failed to match any schema with compatible: 
['wl_355608_a8']

doc reference errors (make refcheckdocs):

See 
https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20240524103506.187277-2-r...@testtoast.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
