Several the Waveshare DSI LCD panel kits use DSI2LVDS ICN6202 bridge
together with the LVDS panels. Define new compatible for the on-kit
bridge setup (it is not defailed and it uses Waveshare prefix since the
rest of the integration details are not known).

If you know the hardware bridge used, should not it be the front
compatible (with waveshare,dsi2lvds fallback)? Or even alone? Can the
waveshare kits come with different bridges? I guess yes, they could.

Please also update at least description:
"...converts DSI to DPI or LVDS."
or similar.

Best regards,

After additional thought (and an email to Marek): the actual ICN bridge
chip is an integrated entity. It is not (and it should not) be
programmed by the host. The kit handles it internally. As such, I don't
think we should be a part of the DT.

I assume so. I have only several samples. Probably we can decode it from
the kit images, when available.
