ANX6345 LVTTL->eDP video bridge, driver with device tree bindings.
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
