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. > > Regards, > kikuchan.

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

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. > >> >> +compatible = "wl_355608_a8"; > Not _s :) Noted, ta.

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. > >> +compatible = "wl_355608_a8"; > > > > This doesn't match what you documented, be sure to run dt_binding_check. > > Thanks, changed underscore to dash mid-patch and neglected to fix all > the examples (and the subsequent code patch it seems.
