dt-bindings: media: i2c: add MAX9296A, MAX96716A, MAX96792A
The MAX9296A deserializer converts single or dual serial inputs to MIPI CSI-2 outputs. The GMSL2 links operate at a fixed rate of 3Gbps or 6Gbps in the forward direction and 187.5Mbps in the reverse direction. In GMSL1 mode, each serial link can be paired with 3.12Gbps or 1.5Gbps GMSL1 serializers or operate up to 4.5Gbps with GMSL2 serializers with GMSL1 backward compatibility. The MAX9296A supports mixed GMSL2 and GMSL1 links. The serial inputs operate independently, allowing videos with different timings and resolutions to be received on each input. MAX96716A supports both tunnel and pixel mode. MAX96792A supports both tunnel and pixel mode, and has two GMSL3 links.

The MAX9296A deserializer converts single or dual serial inputs to
|
||||
MIPI CSI-2 outputs. The GMSL2 links operate at a fixed rate of 3Gbps
|
||||
or 6Gbps in the forward direction and 187.5Mbps in the reverse
|
||||
direction. In GMSL1 mode, each serial link can be paired with 3.12Gbps
|
||||
or 1.5Gbps GMSL1 serializers or operate up to 4.5Gbps with GMSL2
|
||||
serializers with GMSL1 backward compatibility. The MAX9296A supports
|
||||
mixed GMSL2 and GMSL1 links. The serial inputs operate independently,
|
||||
allowing videos with different timings and resolutions to be received
|
||||
on each input.
|
||||
|
||||
MAX96716A supports both tunnel and pixel mode.
|
||||
|
||||
MAX96792A supports both tunnel and pixel mode, and has two GMSL3 links.
