Subject: [PATCH v4 0/2] Add support of Lontium lt8912 MIPI to HDMI bridge

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.
