As far as I can tell the Innolux TV123WAM isn't a real panel and but it's a mosh between the TI TV123WAM and the Innolux P120ZDG-BF1. Let's unmosh. Here's my evidence: * Searching for TV123WAM on the Internet turns up a TI panel. While it's possible that an Innolux panel has the same model number as the TI Panel, it seems a little doubtful. Looking up the datasheet from the TI Panel shows that it's 1920 x 1280 and 259.2 mm x 172.8 mm. * As far as I know, the patch adding the Innolux Panel was supposed to be for the board that's sitting in front of me as I type this (support for that board is not yet upstream). On the back of that panel I see Innolux P120ZDZ-EZ1 rev B1. * Someone pointed me at a datasheet that's supposed to be for the panel in front of me (sorry, I can't share the datasheet). That datasheet has the string "p120zdg-bf1" * If I search for "P120ZDG-BF1" on the Internet I get hits for panels that are 2160x1440. They don't have datasheets, but the fact that the resolution matches is a good sign. While we doing the rename, also mention that no-hpd can be used with this panel. See the previous patch in this series ("drm/panel: simple: Add "no-hpd" delay for Innolux TV123WAM").
