The LT7911EXC is an I2C-controlled bridge that Receiver eDP1.4
and output signal/dual port mipi. This series introduces:
- A device tree binding YAML file describing the hardware
- A new DRM bridge driver implementing the basic functionality
Signed-off-by: Sunyun Yang<syyang@lontium.com>

Change in v1:
- dt-binding:
1. reset pins use active low. [Dmitry]
- drm/bridge:
1. use atomic_* callbacks. [Quentin]
2. fix the incorrect formatting and spaces.
3. add the required header files. [Dmitry]
4. remove "enabled" flag.
5. remove *fw from the lt7911exc struct.
6. .max_register and .range_max use actual range.
7. regulator use bulk interface.
8. use dev_err_probe, devm_mutex_init and devm_drm_bridge_add.
9. Replace GPL with GPL v2.
