[PATCH v3 0/8] imx7/imx8mm media / csi patches

[PATCH v3 0/8] imx7/imx8mm media / csi patches

[Alexander Stein]

Hey everyone,

thanks for the feedback in v2.

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

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.

[PATCH v3 1/8] media: imx: Store the type of hardware implementation

[Alexander Stein]

From: Dorota Czaplejewicz <dorota.czaplejewicz@puri.sm>

The driver covers i.MX5/6, as well as i.MX7/8 hardware.
Those implementations differ, e.g. in the sizes of buffers they accept.

Some functionality should be abstracted, and storing type achieves that.

Note: This is a temporary solution until the imx7-media-csi driver gets
decoupled from the helpers shared with the i.MX6 implementation, and
should be reverted once this happens.

[PATCH v3 2/8] media: imx: Forward type of hardware implementation

[Alexander Stein]

From: Dorota Czaplejewicz <dorota.czaplejewicz@puri.sm>

Pass down the hardware type so imx_media_mbus_fmt_to_pix_fmt can do
the actual switch.

[PATCH v3 4/8] media: imx: Fail conversion if pixel format not supported

[Alexander Stein]

From: Dorota Czaplejewicz <dorota.czaplejewicz@puri.sm>

imx_media_find_mbus_format has NULL as a valid return value,
therefore the caller should take it into account.

[PATCH v3 5/8] media: imx: imx7_media-csi: Add support for additional Bayer patterns

[Alexander Stein]

imx7_csi_configure() allows configuring these Bayer patterns when
starting a stream. So allow these in link_validate() as well.

[PATCH v3 6/8] media: imx: utils: Add more Bayer formats

[Alexander Stein]

Without this the ioctl VIDIOC_ENUM_FMT will not list the 10/12/14-Bit
Bayer formats. This in return results in
"v4l2-ctl --set-fmt-video pixelformat='RG10'" failing to set the
pixelformat.

[PATCH v3 7/8] media: imx: utils: initialize local variable

[Alexander Stein]

imx_media_enum_mbus_formats might not set code at all, this would result
in imx_media_find_mbus_format using an uninitialized variable.
Set code to 0 to avoid returning a wrong pixel format.
