[PATCH 0/2] media: v4l: Add support for the Cadence MIPI-CSI2RX

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Hi,

Here is an attempt at supporting the MIPI-CSI2 RX block from Cadence.

This IP block is able to receive CSI data over up to 4 lanes, and
split it to over 4 streams. Those streams are basically the interfaces
to the video grabbers that will perform the capture.

It is able to map streams to both CSI datatypes and virtual channels,
dynamically. This is unclear at this point what the right way to
support it would be, so the driver only uses a static mapping between
the virtual channels and streams, and ignores the data types.

This serie depends on the patch "v4l: async: add subnotifier
registration for subdevices" from Niklas Söderlund.

Let me know what you think!
