Hi,
attached is a series of our work in progress i.MX6 capture drivers.
I'm posting this now in reaction to Steve's i.MX6 Video capture series,
as a reference for further discussion.
Of the Image Converter (IC) we only use the postprocessor task, with
tiling for larger frames, to implement v4l2 mem2mem scaler/colorspace
converter and deinterlacer devices.
The capture code capture code already uses the media controller framework
and creates a subdevice representing the CSI, but the path to memory is
fixed to IDMAC via SMFC, which is the only possible path for grayscale
and and anything with multiple output ports connected
to the CSIs (such as the CSI2IPU gasket on i.MX6) doesn't work yet. Also,
I think the CSI subdevice driver should be completely separate from the
capture driver.
regards
Philipp
