Changes from v2: * use SPDX-IDs throughout * removed the panel output again, as it was not what Maxime had in mind. At least the Teres-I does very well without. No connector spec, no "quirks"[1], just plain EDID at work. * binding clarifications and cosmetic changes as suggested by Andrzej Changes from v1: * fixed up copyright information. Most code changes are only moves and thus retain copyright and module ownership. Even the new analogix-anx6345.c originates from the old 1495-line analogix-anx78xx.c, with 306 insertions and 987 deletions (ignoring the trivial anx78xx -> anx6345 replacements) 306 new vs. 508 old... * fixed all minor formatting issues brought up * merged previously separate new analogix_dp_i2c module into existing analogix_dp * split additional defines into a preparatory patch * renamed the factored-out common functions anx_aux_* -> anx_dp_aux_*, because anx_...aux_transfer was exported globally. Besides, it is now GPL-only exported. * moved chip ID read into a separate function. * keep the chip powered after a successful probe. (There's a good chance that this is the only display during boot!) * updated the binding document: LVTTL input is now required, only the output side description is optional. Laurent: I have also looked into the drm_panel_bridge infrastructure, but it's not that trivial to convert these drivers to it. Changes from the respective previous versions: * the reset polarity is corrected in DT and the driver; things should be clearer now. * as requested, add a panel (the known innolux,n116bge) and connect the ports. * renamed dvdd?? to *-supply to match the established scheme * trivial update to the #include list, to make it compile in 5.2 -------------- [1] I hesitate to associate information about a connected panel with that term. But should it be neccessary for maximum power saving (e.g. pinebooks), it would be good to have something here, regardless of nomenclature. Torsten
