[PATCH v3 00/15] media: i2c: imx290: Mono support, minor fixes, alternate INCK, and more controls

[Laurent Pinchart]

Hello,

This patch series combines the "[PATCH v2 0/2] Add support for mono
version of Sony IMX290 sensor" ([1]) and "[PATCH v2 00/13] imx290: Minor
fixes, support for alternate INCK, and more ctrls" ([2]) previously
submitted by Dave into a single series.

As promised in my review of v2 of both series, I have tested the changes
with my IMX327 camera sensor, connected to the i.MX8MP ISP, with
libcamera. I haven't noticed any regression (but, full disclaimer, I
haven't tested all the newly features). I think we're thus good to go.

This version handles all review comments from v2, resulting in the
following changes:

- Deprecate the sony,imx290 compatible
- Update the DT example to use the new sony,imx290lqr compatible
- Drop unneeded pointer cast
- Don't move imx290_of_match table
- Fix typos

The code has also been rebased on top of the latest media master branch,
with rebase conflicts and rebase-induced compilation breakages fixed.

The patches are available from

[PATCH v3 01/15] media: dt-bindings: media: i2c: Add mono version to IMX290 bindings

[Laurent Pinchart]

From: Dave Stevenson <dave.stevenson@raspberrypi.com>

The IMX290 module is available as either monochrome or colour and
the variant is not detectable at runtime.

Add a new compatible string for the monochrome version, based on the
full device name IMX290LLR. For consistency, add a new compatible string
for the colour version based on the IMX290LQR full device name, and
deprecate the current ambiguous compatible string.

[PATCH v3 02/15] media: i2c: imx290: Add support for the mono sensor variant

[Laurent Pinchart]

From: Dave Stevenson <dave.stevenson@raspberrypi.com>

The IMX290 module is available as either mono or colour (Bayer).

Update the driver so that it can advertise the correct mono
formats instead of the colour ones.

[Laurent Pinchart]

From: Dave Stevenson <dave.stevenson@raspberrypi.com>

Any V4L2 subdevice that implements controls and declares
V4L2_SUBDEV_FL_HAS_DEVNODE should also declare V4L2_SUBDEV_FL_HAS_EVENTS
and implement subscribe_event and unsubscribe_event hooks.

This driver didn't and would therefore fail v4l2-compliance

Add the relevant hooks.

[PATCH v3 06/15] media: i2c: imx290: Fix the pixel rate at 148.5Mpix/s

[Laurent Pinchart]

From: Dave Stevenson <dave.stevenson@raspberrypi.com>

The datasheet lists the link frequency changes between
1080p and 720p modes. This is correct that the link frequency
changes as measured on an oscilloscope.

Link frequency is not necessarily the same as pixel rate.

The datasheet gives standard configurations for 1080p and 720p
modes at a number of frame rates.
Looking at the 1080p mode it gives:
HMAX = 0x898 = 2200
VMAX = 0x465 = 1125
2200 * 1125 * 60fps = 148.5MPix/s

Looking at the 720p mode it gives:
HMAX = 0xce4 = 3300
VMAX = 0x2ee = 750
3300 * 750 * 60fps = 148.5Mpix/s

This driver currently scales the pixel rate proportionally to the
link frequency, however the above shows that this is not the
correct thing to do, and currently all frame rate and exposure
calculations give incorrect results.

Correctly report the pixel rate as being 148.5MPix/s under any
mode.

[PATCH v3 07/15] media: i2c: imx290: Support 60fps in 2 lane operation

[Laurent Pinchart]

From: Dave Stevenson <dave.stevenson@raspberrypi.com>

Commit "97589ad61c73 media: i2c: imx290: Add support for 2 data lanes"
added support for running in two lane mode (instead of 4), but
without changing the link frequency that resulted in a max of 30fps.

Commit "98e0500eadb7 media: i2c: imx290: Add configurable link frequency
and pixel rate" then doubled the link frequency when in 2 lane mode,
but didn't undo the correction for running at only 30fps, just extending
horizontal blanking instead.

Remove the 30fps limit on 2 lane by correcting the register config
in accordance with the datasheet for 60fps operation over 2 lanes.

[PATCH v3 09/15] media: i2c: imx290: Convert V4L2_CID_HBLANK to read/write

[Laurent Pinchart]

From: Dave Stevenson <dave.stevenson@raspberrypi.com>

The driver exposed V4L2_CID_HBLANK as a read only control to allow
for exposure calculations and determination of the frame rate.

Convert to a read/write control so that the frame rate can be
controlled.

[PATCH v3 10/15] media: i2c: imx290: Convert V4L2_CID_VBLANK to read/write

[Laurent Pinchart]

From: Dave Stevenson <dave.stevenson@raspberrypi.com>

The driver exposed V4L2_CID_VBLANK as a read only control to allow
for exposure calculations and determination of the frame rate.

Convert to a read/write control so that the frame rate can be
controlled.
V4L2_CID_VBLANK also sets the limits for the exposure control,
therefore exposure ranges have to be updated when vblank changes
(either via s_ctrl, or via changing mode).

[PATCH v3 11/15] media: i2c: imx290: VMAX is mode dependent

[Laurent Pinchart]

From: Dave Stevenson <dave.stevenson@raspberrypi.com>

The default VMAX for 60fps in 720p mode is 750 according to the
datasheet, however the driver always left it at 1125 thereby stopping
60fps being achieved.

Make VMAX (and therefore V4L2_CID_VBLANK) mode dependent so that 720p60
can be achieved.

[PATCH v3 14/15] media: i2c: imx290: Add support for H & V Flips

[Laurent Pinchart]

From: Dave Stevenson <dave.stevenson@raspberrypi.com>

The sensor supports H & V flips, so add the relevant hooks for
V4L2_CID_HFLIP and V4L2_CID_VFLIP to configure them.

Note that the Bayer order is maintained as the readout area
shifts by 1 pixel in the appropriate direction (note the
comment about the top margin being 8 pixels whilst the bottom
margin is 9). The V4L2_SEL_TGT_CROP region is therefore
adjusted appropriately.

Re: [PATCH v3 00/15] media: i2c: imx290: Mono support, minor fixes, alternate INCK, and more controls

[Alexander Stein]

Hi Laurent,

thanks for the wrap-up.
I could test this series on my TQMa8MPxL (i.MX8MP) using ISP and libcamera as 
well. I think as well that we're good to go.

Best regards,
Alexander

What is the status of this series? Will it be picked up?

I expect Sakari to pick it up for v6.4. I have pushed the whole series
with acks to the next/media/sensors/imx290 branch on
git://git.kernel.org/pub/scm/linux/kernel/git/pinchartl/linux.git.
