With this set I was able to capture video frames from a MIPI CSI-2 camera in my TQMa8MQML + MBA8MX hardware. The actual camera used is a Vision Components 'VC MIPI IMX327 C' camera. IMX327 is compatible to IMX290. Patch 8 shows the DT overlay I'm using, not suitable for merging. Please ignore the FPGA part, this is mainly for power supply and GPIO reset line. This is currently a custom driver I'm working on, but I do not want to focus on in this series. Please note I tested this only on this imx8 platform. First thanks to Dorota for the patchset at [1] (patches 1-4) which is necessary to capture correct images. I integrated Hans' review into it. I hope the I didn't make a mistake and the original author is kept along. I used v4 for that patchset, it is v1 again in this set. I hope this is not confusing. Starting from patch 5 there are small fixes which allows me to configure my media device. Device configuration: ``` media-ctl -l "'imx290 2-001a':0->'csis-32e30000.mipi-csi':0 [1]" media-ctl -V "'imx290 2-001a':0 [fmt:SRGGB10_1X10/1920x1080 field:none colorspace:raw]" media-ctl -V "'csi':0 [fmt:SRGGB10_1X10/1920x1080 field:none colorspace:raw]" v4l2-ctl -d0 --set-fmt-video width=1920,height=1080,pixelformat='RG10',field=none media-ctl -p ``` The media-ctl topology is: ``` # media-ctl -p Media controller API version 5.17.0 Media device information ------------------------ driver imx7-csi model imx-media serial bus info platform:32e20000.csi hw revision 0x0 driver version 5.17.0 Device topology - entity 1: csi (2 pads, 2 links) type V4L2 subdev subtype Unknown flags 0 device node name /dev/v4l-subdev0 pad0: Sink [fmt:SRGGB10_1X10/1920x1080 field:none colorspace:raw xfer:none ycbcr:601 quantization:full-range] <- "csis-32e30000.mipi-csi":1 [ENABLED,IMMUTABLE] pad1: Source [fmt:SRGGB10_1X10/1920x1080 field:none colorspace:raw xfer:none ycbcr:601 quantization:full-range] -> "csi capture":0 [ENABLED,IMMUTABLE] - entity 4: csi capture (1 pad, 1 link) type Node subtype V4L flags 0 device node name /dev/video0 pad0: Sink <- "csi":1 [ENABLED,IMMUTABLE] - entity 10: csis-32e30000.mipi-csi (2 pads, 2 links) type V4L2 subdev subtype Unknown flags 0 device node name /dev/v4l-subdev1 pad0: Sink [fmt:SRGGB10_1X10/1920x1080 field:none colorspace:raw xfer:709 ycbcr:601 quantization:lim-range] <- "imx290 2-001a":0 [ENABLED] pad1: Source [fmt:SRGGB10_1X10/1920x1080 field:none colorspace:raw xfer:709 ycbcr:601 quantization:lim-range] -> "csi":0 [ENABLED,IMMUTABLE] - entity 15: imx290 2-001a (1 pad, 1 link) type V4L2 subdev subtype Sensor flags 0 device node name /dev/v4l-subdev2 pad0: Source [fmt:SRGGB10_1X10/1920x1080 field:none colorspace:raw] -> "csis-32e30000.mipi-csi":0 [ENABLED] ``` Note: MIPI CSI settle times are not calculated correctly right now and need a manual overwrite: echo 13 > /sys/kernel/debug/32e30000.mipi-csi/ths_settle echo 2 > /sys/kernel/debug/32e30000.mipi-csi/tclk_settle I ignored the settings for xfer, ycbcr and quantization for now. I do neither know how they will affect me nor what it should be. Also I did not focus on v4l2-compliance tool, this is a further task as well. IMHO imx7-mipi-csis.c should also create an immutable link to the camera sensor.
