Sorry my bad, yes add me it's fine

??? why not chipwealth,ch13726a ??
Because this is a driver chip that supports multiple panels. The
driver code I based on also supports the retroid pocket 5 panel, which
has a different resolution. Similar naming is used in the rocktech
jh057n00900 binding, which is why I picked this compatible.
It doesn't work like that, add a compatible per physical device, not
by driver. You can add common fallbacks if the panel is the same as another.
