Subject: [PATCH 0/4] drm/bridge: lt8912b: Fix corrupt display output due to wrong bridge config

From: Philippe Schenker <philippe.schenker@...adex.com>

This patch-set fixes the lt8912b driver that currently does not take
care whether or not the attached display has postiive or negative syncs
and or reports on EDID if it needs HDMI mode or DVI.

This series addresses also an issue where the LVDS startup sequence was
written to the wrong I2C address (the lt8912 has three). This caused
writing into reserved registers and causing an unstable HDMI picture
that manifests itself only sometimes and depending on the monitor with a
flickering and a repeating of going black and coming up again. While at
it move also some sensible comments to the sequence.
