I know that later on we embed this media dev in csi, but meanwhile we
can reach here where csi->imxmd is NULL, because...

Didn't this notifier got dropped in cleanup() function? or am I
missing something?

This can't happen, as if probe() fails, remove() isn't called.

They should be kept in imx7_csi_media_cleanup() and removed later. I'll
fix it too.

Prepare for the decoupling of the imx7-media-csi driver from the
IPUv3-based drivers by moving the imx_media_dev handling from probe()
function to separate functions.
Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

Changes since v1:
- Set csi->imxmd earlier in imx7_csi_media_init()
- Unregister and cleanup notifier in imx7_csi_media_cleanup()

To prepare for code refactoring, copy the V4L2 async notifier helper
code used by this driver verbatim from imx-media-dev-common.c. Rename
some functions to avoid name clashes. No functional change included.

The imx_media_create_csi2_links() creates a media controller link
between the CSI-2 receiver and the next entity in the pipeline, which
can be either a video mux (handled by the video-mux driver) or the CSI
bridge itself. This isn't needed, as the link is already created either
by the video-mux driver or by the imx7-media-csi driver itself (in
imx7_csi_notify_bound()).
Drop imx_media_create_csi2_links(), which allows dropping the CSI bridge
subdev grp_id.

The V4L2 async notifier embedded in the imx_media_dev structure is
triggered when the CSI bridge subdev is registered. We don't need an
async notifier for this, as we can call the .complete() handler directly
from the CSI bridge subdev .registered() handler.

The imx_media_dev framework maintains a per-pad list of connected video
devices, created once all subdevs have been bound. This is used for two
purposes, updating V4L2 control inheritance when links change, and
relaying subdev events to video nodes. None of these are used by the
imx7-media-csi driver as it implements the MC-centric approach. Drop
them.

The frame_interval field of the imx7_csi structure is set but never
used. Drop it.

There's no need to wait until the subdev is registered to initialize the
active pad formats. Do so at probe time.

From: Paul Elder <paul.elder@ideasonboard.com>
imx_media_of_add_csi() from imx-media-of.c validates that the fwnode for
the CSI bridge is enabled, and adds the fwnode to the async notifier of
the imxmd. The former is redundant, as if the CSI bridge driver probes,
clearly it is enabled in the DT. The latter is not needed as the imxmd
notifier isn't used anymore. The call is thus not needed and can be
dropped. This removes the dependency of imx7-media-csi.c on
imx-media-of.c.

To prepare for code refactoring, copy the video device helper code used
by this driver verbatim from imx-media-capture. Rename some functions to
avoid name clashes, and leave the legacy ioctls out as they're not used
by the imx7-media-csi driver. No functional change included.

To prepare for code refactoring, copy the imx_media_dev_init() helper
used by this driver from imx-media-dev-common.c. Rename the function to
avoid name clashes, and leave the v4l2_device notify handler out as it
only serves to implement control inheritance, which this driver doesn't
use. No functional change intended.

There's no need anymore to allocate the imx_media_dev structure
separately from imx7_csi. Embed it.

There's no need to call imx_media_add_video_device() anymore, as the
video devices list it manages is only used by the control inheritance
mechanism in the helpers, which this driver doesn't use.

The imx_media_dev structure contains three fields that are not used by
this driver or any helper code that it calls. Don't initialize them.

To prepare for code refactoring, copy the
imx_media_pipeline_set_stream() helper used by this driver from
imx-media-utils.c. Rename the function to avoid name clashes, no
functional change intended.

Simplify the imx7_csi_media_pipeline_set_stream() function by passing it
the imx7_csi pointer, which avoids going from subdev to entity and back
to subdev.

The imx7_csi_media_pipeline_set_stream() function has separate branches
for the start and stop paths, surrounded by mutex lock/unlock. That is
very little shared code, inline the locking and corresponding branch in
each of the two callers.

Now that the driver doesn't use any helper that relies on the
imx_media_dev structure anymore, merge the three fields of the
imx_media_dev structure directly in the imx7_csi structure. Update all
the users accordingly.

Decouple from the imx_media_buffer structure defined in shared helpers
by duplicating it in the imx7-media-csi driver. No functional change
intended.

Now that the driver doesn't use any helper that relies on the
imx_media_video_dev structure anymore, merge its fields directly in the
imx7_csi structure. Update all the users accordingly, and drop the list
field that isn't used by the driver.

Decouple from the imx_media_dma_buf structure defined in shared helpers
by duplicating it in the imx7-media-csi driver, along with the two small
alloc and free functions. No functional change intended.

The kernel memory allocators already complain loudly to the log when
allocation fails. There's no need for an additional message.

Replace the enum ipu_color_space cs field in struct imx7_csi_pixfmt with
a bool yuv field. This decouples the driver from the unrelated IPUv3
headers.

The imx7_csi_try_colorimetry() function supports the unrelated image

A large number of formats defined in the pixel_formats array are not
supported, as shown by the switch-case check in
imx7_csi_pad_link_validate(). Drop them.

I'll add a comment above the formats array that mentions this. Same for
the comment on had on patch 44/50. I'll refrain from posting a v2 until
I get more review as I don't want to spam the list too often.

Define a macro for the default media bus code and use it through the
driver to replace a hardcoded value and a dynamic query from the
pixel_formats table.

When trying a format on the subdev sink pad, if the requested media bus
code isn't supported, fallback to the default with a simpler logic.

Inline the imx7_csi_init_mbus_fmt() function in its only caller. This
allows simplifying the code.

This change now expects that V4L2_PIX_FMT_UYVY is the 1st entry in
pixel_formats. Maybe a comment is helpful to indicate
that.

The list of supported formats comes from helpers shared with the i.MX6
IPUv3 and is incorrect in multiple regards:
- 10-, 12- and 14-bit Bayer formats are stored in memory as SBGGR10,
SBGGR12 and SBGGR14 respectively (plus components permutations), not
SBGGR16. Same thing for greyscale formats.
- 16-bit RAW formats are not supported by the hardware.
Fix the supported formats table.

The device supports 14-bit greyscale formats the same way it supports
14-bit Bayer formats.

The driver won't accept unsupported pixel formats, there's thus no need
to validate it in imx7_csi_pad_link_validate().

The only event that the driver allows subscribing to,
V4L2_EVENT_IMX_FRAME_INTERVAL_ERROR, is never generated. Drop events

None of the shared helpers are used anymore. Make this official by
dropping inclusion of imx-media.h.

I went over all patches and I have 2 small remarks:
1. Shouldn't we change the connection between imx-media objects and
imx7-csi also in kconfig? Since at the end of this series they are
completely independent. Yeah, it can be done in a follow up
patch on the unstaging, for me that's fine also.
2. Something that caught my eye on patch 2/50. But nothing functional.
Once again many thanks for continuing investing in this code.
for the all series (except patch 2/50):

I was thinking of doing it while destaging, as I found it a bit
pointless to reorganize Kconfig in staging to then immediately move the
driver out of staging, but I don't mind already handling this in staging
if preferred.

Thanks for putting me on CC. I'll try to get my system running your patches
ASAP.

As only minor changes were needed, I ended up posting v1.1 of the
corresponding patches instead of spamming everybody with a full v2. For
your convenience, I've pushed the result to
git://linuxtv.org/pinchartl/media.git imx7/destage
I know it's a bit of a short notice, but I'd like to send a pull request
in time for v5.20, when do you think you would be able to test the
series ?

I happen to have my setup already available, so I could test your updated
series pretty fast.
Accessing imx327 still works for WIP config. So

Thanks a lot for the quick testing. I've now sent the pull request.
Do you plan to submit a new version of your patches on top of this ?

The patches regarding the imx[,7]-media-* are not needed anymore, they are
obsolete now. There are only patches regarding DT overlay and the Vision
Components FPGA and sensors I'm working on right now.

Thanks again for this patchset. This does not only simplify my series, it
pretty much makes it obsolete. Only one change is still valid (rounding up
width depending on bpp), but I would skip that for now.
Just using my DT is enough. Nice!
If you respin a v2, I'll retest again for a proper Tested-by tag.
Regards,
Alexander
