Hi,

This series adds support for Lontium LT9611UXC bridge chip which takes
MIPI DSI as input and provides HDMI signal as output.

The chip can be found in Qualcomm RB5 platform [1], [2].

[2] https://www.thundercomm.com/app_en/product/1590131656070623

Changes since v2:
 - Squashed connector support into main patch
 - Added comment on modes table
 - Dropped display timings support, covered by EDID
 - Dropped sleep mode support
 - Dropped hpd_status reading from ISR handler
 - Added "sentinel" comments to empty table entries

Changes since v1:
 - Fix whitespaces/indentation
 - Support working without DRM_BRIDGE_ATTACH_NO_CONNECTOR

Sorry for taking so long time to get back to you.
Which display driver will this be used together with?

The preference is that the display driver adds support for
creating the connector so we can drop this from the bridge
as this is not how things should be done these days.

All the rest looked good.
