Changes in v3: * Dropped PATCH v2 5/9, applied in commit a7a52e146d0e * Added R-b Laurent Pinchart to PATCH 1 & 4 * Fix bpp check in PATCH 3 Below is the original message slightly modified to match the v3 changes. This is a set of patch for imx7 media drivers based on next-20220308. 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. 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] <- "imx290 2-001a":0 [ENABLED] pad1: Source [fmt:SRGGB10_1X10/1920x1080 field:none colorspace:raw] -> "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 did not focus on v4l2-compliance tool, this is a future task.
