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].

Changes since v3:
- Support for firmware upgrades
- Simplified modes table to include only used fields (w, h, refresh)
- Added more entries to display modes table, as more modes are
supported by the firmware
- Wait for EDID to be available from the hardware before reading it
- Do not store EDID in the interim buffer, lowering the size of
per-device struct
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
