This is v14 of a 2-patch series adding a DRM bridge driver for the Lontium LT7911EXC eDP-to-MIPI-DSI bridge chip. The series has gone through extensive review iterations (14 versions), with many prior bugs caught and fixed. The DT binding (patch 1) already has a Reviewed-by from Krzysztof Kozlowski, and the driver (patch 2) has a Reviewed-by from Dmitry Baryshkov.

The driver is relatively straightforward: it provides a DRM bridge with a built-in MIPI DSI host, firmware upgrade via sysfs, and GPIO/regulator management. Display timing is handled entirely by the chip's internal firmware.

**Overall assessment: The series is in reasonable shape for a v14, but several issues remain that should be addressed before merge.**

The most notable remaining concerns are:
1. The `.detach` callback incorrectly NULLs `bridge->dev` — that's the DRM core's job
2. The firmware upgrade path has locking gaps after `lt7911exc_reset()` calls
3. Minor style and Kconfig issues
