[PATCH 0/9] media: rockchip: rkcif: add support for rk3588 vicap

[Michael Riesch via B4 Relay]

Habidere,

The RK3588 Video Capture (VICAP) constitutes an essential piece of the
RK3588 camera interface with one DVP, six MIPI CSI-2 receivers,
scale/crop units, and a data path multiplexer (to scaler units, to ISP,
...). This series introduces basic support for the RK3588 VICAP unit
to the rkcif driver, thus paving the way for video capture in general
and for camera sensor image processing in particular.

The changes have been tested successfully on a Radxa ROCK 5B+ with two
Radxa 4K cameras attached to it. The raw images from the sensors can
be streamed after configuring the hardware pipeline with

media-ctl -d 0 --set-v4l2 '"dw-mipi-csi2rx fdd30000.csi":0 \
  [fmt:SGBRG10_1X10/3864x2192 field:none colorspace:raw xfer:none]'
media-ctl -d 0 --set-v4l2 '"rkcif-mipi2":0 \
  [fmt:SGBRG10_1X10/3864x2192 field:none colorspace:raw xfer:none]'
media-ctl -d 0 --set-v4l2 '"dw-mipi-csi2rx fdd50000.csi":0 \
  [fmt:SGBRG10_1X10/3864x2192 field:none colorspace:raw xfer:none]'
media-ctl -d 0 --set-v4l2 '"rkcif-mipi4":0 \ 
  [fmt:SGBRG10_1X10/3864x2192 field:none colorspace:raw xfer:none]'

and using e.g., GStreamer

gst-launch-1.0 v4l2src \
  device=/dev/v4l/by-path/platform-fdce0000.video-capture-video-index0 \
  ! video/x-bayer,format=gbrg10le,width=3864,height=2192 ! bayer2rgb \
  ! ...
(or -index4 for the other camera sensor).

Note that this series requires the RK3588 MIPI CSI-2 receiver patches
[0]. I included them here to provide the possibility to test the changes
without any nasty merge conflicts.

Looking forward to your comments!
