Hi,
this patch set adds the support of the Lontium lt8912 MIPI to HDMI
bridge in the kernel.

It's only support the video part, not the audio part yet
since I don't have the datasheet of this component.
I get the current i2c configuration from Digi and
Boundary drivers.
Developed using the DB_DSIHD board from BoundaryDevices.

Update in v2
  - Use standard data-lanes instead of a custom prop;
  - Use hdmi-connector node.

Update in v3
  - Fix indentation;
  - Implement missing bridge functions;
  - Add some comments.

Update in v4
  - Fix bridge ops;
  - Fix i2c error detection.
