[PATCH 1/2] dt-bindings: drm/panel: simple: add lg,acx467akm-7 panel

[Brian Masney]

Add binding for the LG ACX467AKM-7 4.95" 1080×1920 LCD panel that is
found on the LG Nexus 5 (hammerhead) phone. This appears to be a JDI
panel based on some Internet searches, however a specific model number
could not be found. I disassembled an old Nexus 5 with a broken
screen and the LG part number is the only model number present on the
back of the panel, so I think that is probably the best ID to use.

See patch 1 in this series for why I went with the LG model number.

Tell me if you need me to merge this to the DRM misc tree.

It would be great if you could take this patch, plus the corresponding
change to panel-simple.c [1]

Both patches applied to drm-misc-next (will be in v5.2). Sorry for taking so
long, I had some urgent other priorities.
