[PATCH 0/2] arm64: dts: rockchip: enable OV9281 CAM0 and CAM1 on RK3588 Jaguar

[Quentin Schulz]

RK3588 Jaguar has two proprietary camera connectors, P14 and P15. This
adds support for the only camera module we currently have for this
connector.

The camera module has a 2-lane OV9281 camera sensor, an IMU, a
magnetometer and an EEPROM.

We have new camera modules based on an OV13850 that should be coming up
soon, hence why I made the support into their own separate DTSO instead
of directly integrating them in the main DTS.

Known issues:
- lis2mdl driver currently doesn't support being instantiated twice, so
  only one magnetometer will show up, if the two cameras modules are
  connected,
- OV9281 test patterns (no upstream support) returns broken patterns,
  see discussion on IRC
  https://libera.catirclogs.org/linux-rockchip/2026-11-02, the image I
  get without the test pattern *looks* okay to my non-expert eyes. In
  any case, it's unlikely to be an issue in the Device Tree,

Image capture test:
  #!/usr/bin/env bash

  set -o pipefail
  set -eux

  CAM=$1
  COLORFMT=$2
  SIZE=$3

  if [ "$COLORFMT" = "GREY" ] || [ "$COLORFMT" = "Y8" ]; then
  	MEDIACTLFMT="fmt:Y8_1X8/$SIZE field:none colorspace:raw xfer:none"
  	BITDEPTH=8
  else
  	MEDIACTLFMT="fmt:Y10_1X10/$SIZE field:none colorspace:raw xfer:none"
  	BITDEPTH=10
  fi

  if [ "$CAM" = "P14" ]; then
  	MEDIACTL_SENSOR="ov9281 2-0060"
  	MEDIACTL_RKCIF="rkcif-mipi2"
  	MEDIACTL_CSIRX="dw-mipi-csi2rx fdd30000.csi"
  else
  	MEDIACTL_SENSOR="ov9281 7-0060"
  	MEDIACTL_RKCIF="rkcif-mipi4"
  	MEDIACTL_CSIRX="dw-mipi-csi2rx fdd50000.csi"
  fi

  for dev in /sys/class/video4linux/video*/; do
  	if [ "$(cat "$dev/name")" != "$MEDIACTL_RKCIF-id0" ]; then
  		continue
  	fi
  
  	VIDEODEV=$(basename "$dev")
  	break
  done

  media-ctl -d 0 --set-v4l2 "'$MEDIACTL_SENSOR':0 [$MEDIACTLFMT]"
  media-ctl -d 0 --set-v4l2 "'$MEDIACTL_RKCIF':0 [$MEDIACTLFMT]"
  media-ctl -d 0 --set-v4l2 "'$MEDIACTL_CSIRX':0 [$MEDIACTLFMT]"
  # Name the file a format YUView can recognize automatically
  /root/yavta/build/yavta -f"$COLORFMT" -s$SIZE -c1 -n1 /dev/$VIDEODEV -Fframe-#_${SIZE}_${BITDEPTH}b_yuv400.yuv

With yavta[1] and checked with YUView[2] as gstreamer doesn't seem[3] to
have support for Y10.

Ran:
 - ./test-cam.sh P14 Y8 1280x800
 - ./test-cam.sh P15 Y8 1280x800
 - ./test-cam.sh P14 Y10 1280x800
 - ./test-cam.sh P15 Y10 1280x800

Pictures look decent to me.

Wrote random data to the EEPROMs and read it back identical.

Moved the cameras, accel and gyro raw sysfs values changed.

Magnetometers tested individually, with small magnet, raw values
changed.

I've not tested IIO buffers and/or the various interrupts.

Light dependency on
https://lore.kernel.org/linux-media/20261102-v4l-y8-y10-csi-vicap-v2-0-0a4149d96dae@cherry.de/
for it to actually work (no impact on binding or device tree).
