ANX6345 LVTTL->eDP video bridge, driver with device tree bindings. Long time, few but important changes.
Changes since v3:
* converted binding schema file to json-schema ("YAML") It now validates (itself and the dts) like a charm ;-) Input port0 is mandatory, output port1 is optional.
* Enric Balletbo i Serra waived analogix-anx6345 module ownership to icenowy CAFqH_50s0J_NEevV9b5o-wq-bw+xGaUZ3WyhVDRZKyM2Yn-iVg@mail.gmail.com Since they both agree, I won't interfere.
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.
* 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
