Resend due to email message limits being exceeded.
v2 changes:
- Add use macros patch
- Add support for powerdown gpio patch
- Add support for reset gpio patch
- Dropped Add support for long exposure modes patch
- Implemented feedback from Jacopo Mondi
- media: i2c: imx258: Add regulator control
- media: i2c: imx258: Add support for 24MHz clock
- media: i2c: imx258: Add support for running on 2 CSI data lanes
- media: i2c: imx258: Add get_selection for pixel array information
- media: i2c: imx258: Issue reset before starting streaming
- media: i2c: imx258: Set pixel_rate range to the same as the value
- dt-bindings: media: imx258: Add alternate compatible strings
- media: i2c: imx258: Change register settings for variants of the sensor
- media: i2c: imx258: Make HFLIP and VFLIP controls writable
This adds a few more patches and drops one. The long exposure mode patch was
dropped due to the bug that Jacopo found. The powerdown and reset gpio patches
were added as that fixes support for the Pinephone Pro, without them the sensor
doesnt initialize correctly.
Tested on a Pinephone Pro by forcing 24 mhz clock and was able to access all 3
resolutions. The two lower resolutions had some artifacts but that is expected
as more changes are required to fix them for the Pinephone Pro specifically,
kept all registers the same as Dave's original patch since that works on
dedicated imx258 hardware and the artifacts are PPP specific so it shouldnt be
a regression.
v1
This is a set of patches for imx258 that allow it to work with alternate clock
frequencies, over either 2 or 4 lanes, and generally adding flexibility to the
driver.
Tested with an IMX258 module from Soho Enterprises that has a 24MHz oscillator.
Both 2 and 4 lane configurations work with correct link frequencies and pixel
rates.
Jacopo has tested on a PinePhone Pro which has an ~19.2MHz clock fed from the SoC,
He confirms that the two lower resolution modes work, but not the full res mode.
Comparing to the BSP it looks like they have some weird clock configuration in
the 4208x3120 mode (nominally 1224Mb/s/lane instead of 1267).
As it has never previously worked directly with the mainline driver this isn't a
regression but may indicate that there is a need for support of additional link
frequencies in the future.
The last patch that makes HFLIP and VFLIP configurable may be contentious as I've
retained the default configuration of inverted from the original driver. I know
this was discussed recently, but I can't recall the final outcome.
I am relying on someone from Intel testing this out, as correcting the cropping
and supporting flips has changed the Bayer order. Seeing as this is all above
board in V4L2 terms I really hope that the layers above it behave themselves.
Cheers
Dave

The output image is defined as being 4208x3118 pixels in size.
Y_ADD_STA register was set to 0, and Y_ADD_END to 3118, giving
3119 lines total.
The datasheet lists a requirement for Y_ADD_STA to be a multiple
of a power of 2 depending on binning/scaling mode (2 for full pixel,
4 for x2-bin/scale, 8 for (x2-bin)+(x2-subsample) or x4-bin, or 16
for (x4-bin)+(x2-subsample)).
(Y_ADD_END – Y_ADD_STA + 1) also has to be a similar power of 2.
The current configuration for the full res modes breaks that second
requirement, and we can't increase Y_ADD_STA to 1 to retain exactly
the same field of view as that then breaks the first requirement.
For the binned modes, they are worse off as 3118 is not a multiple of
4.
Increase the main mode to 4208x3120 so that it is the same FOV as the
binned modes, with Y_ADD_STA at 0.
Fix Y_ADD_STA and Y_ADD_END for the binned modes so that they meet the
sensor requirements.
This does change the Bayer order as the default configuration is for
H&V flips to be enabled, so readout is from Y_STA_END to Y_ADD_STA,
and this patch has changed Y_STA_END.

* [PATCH 03/23] media: i2c: imx258: Disable digital cropping on binned modes

From: Dave Stevenson <dave.stevenson@raspberrypi.com>
The binned modes set DIG_CROP_X_OFFSET and DIG_CROP_IMAGE_WIDTH
to less than the full image, even though the image being captured
is meant to be a scaled version of the full array size.
Reduce X_OFFSET to 0, and increase IMAGE_WIDTH to the full array.

From: Dave Stevenson <dave.stevenson@raspberrypi.com>
The values and ranges of V4L2_CID_VBLANK are all computed,
so there is no reason for it to be a read only control.
Remove the register values from the mode lists, add the
handler, and remove the read only flag.

From: Dave Stevenson <dave.stevenson@raspberrypi.com>
Out of all the registers that are defined for each mode, only around
10 differ between the modes.
Split the table into common and mode specific ones.

From: Dave Stevenson <dave.stevenson@raspberrypi.com>
Out of all the registers that are defined for each mode, only around
10 differ between the modes.
Split the table into common and mode specific ones.

From: Dave Stevenson <dave.stevenson@raspberrypi.com>
There's no reason why only a clock of 19.2MHz is supported.
Indeed this isn't even a frequency listed in the datasheet.
Add support for 24MHz as well.
The PLL settings result in slightly different link frequencies,
so parameterise those.

From: Dave Stevenson <dave.stevenson@raspberrypi.com>
There's no reason why only a clock of 19.2MHz is supported.
Indeed this isn't even a frequency listed in the datasheet.
Add support for 24MHz as well.
The PLL settings result in slightly different link frequencies,
so parameterise those.

Is Luigi311 your real name? As per

These values aren't used outside the array below and the macro names are
imprecise anyway. Could you put the numerical values to the array instead?

The arrays currently have two entries so this works but it'd nice to have a
bit more robust way to handle differences between the two arrays. Could you
maintain e.g. the number of entries in the array in a struct field perhaps?

Is Luigi311 your real name? As per
Documentation/process/submitting-patches.rst, anonymous (or pseudonym I'd
say as well) contributions are not an option.

The arrays currently have two entries so this works but it'd nice to have a
bit more robust way to handle differences between the two arrays. Could you
maintain e.g. the number of entries in the array in a struct field perhaps?

Luigi311 is not my real name but it would be a lot easier to find me if
it was. My real name is Luis Garcia which is a super common name so its
actually way easier to find me and all my work using my online name of
Luigi311. I can go ahead and swap over to Luis Garcia if required but a
name like that would provide no value in contacting/finding me since I'm
not famous like all the other Luis Garcia's that appear on google.

Would it make more sense to do something like default to index 0 and then use
ARRAY_SIZE to iterate through the array and do a comparison to get the min and
max size so it would always choose the correct value no matter how many entries
there are?

Would it make more sense to do something like default to index 0 and then use
ARRAY_SIZE to iterate through the array and do a comparison to get the min and
max size so it would always choose the correct value no matter how many entries
there are?

Here you're obtaining the list of supported link frequencies from the
firmware but it is not validated (nor it was validated by the driver
previously). I'd regard that a driver bug but fixing it at this point could
introduce adverse effects elsewhere.
I think what I'd do here is that I'd ignore the issue if there are no
frequencies defined for the endpoint but if there are, then enable only
those that are listed in the endpoint.
Could you add a patch to do this, please? v4l2_link_freq_to_bitmap() has
been recently added to facilitate this.

Here you're obtaining the list of supported link frequencies from the
firmware but it is not validated (nor it was validated by the driver
previously). I'd regard that a driver bug but fixing it at this point could
introduce adverse effects elsewhere.
I think what I'd do here is that I'd ignore the issue if there are no
frequencies defined for the endpoint but if there are, then enable only
those that are listed in the endpoint.
Could you add a patch to do this, please? v4l2_link_freq_to_bitmap() has
been recently added to facilitate this.

I can give this a try, it would be similar to this patch that you submitted
earlier for the imx319 here

I can give this a try, it would be similar to this patch that you submitted
earlier for the imx319 here

I believe I got this implemented, added in that v4l2_link_freq_to_bitmap()
and it failed to probe the imx258 device due to missing frequencies so I
checked the device dts and the imx258 had no link-frequencies specified so
added in 321000000 and 636000000 to match the 24mhz and it worked, I then
swapped it over to bogus numbers 311000000 and 626000000 and it complained
about no matching link frequencies found so it failed to probe. Looks
like its working with that new function now. Will include in next revision

I believe I got this implemented, added in that v4l2_link_freq_to_bitmap()
and it failed to probe the imx258 device due to missing frequencies so I
checked the device dts and the imx258 had no link-frequencies specified so
added in 321000000 and 636000000 to match the 24mhz and it worked, I then
swapped it over to bogus numbers 311000000 and 626000000 and it complained
about no matching link frequencies found so it failed to probe. Looks
like its working with that new function now. Will include in next revision

From: Dave Stevenson <dave.stevenson@raspberrypi.com>
V4L2 sensor drivers are expected are expected to clip the supported
exposure range based on the VBLANK configured.
IMX258 wasn't doing that as register 0x350 (FRM_LENGTH_CTL)
switches it to a mode where frame length tracks coarse exposure time.
Disable this mode and clip the range for V4L2_CID_EXPOSURE appropriately
based on V4L2_CID_VBLANK.

From: Dave Stevenson <dave.stevenson@raspberrypi.com>
The sensor supports the clock lane either remaining in HS mode
during frame blanking, or dropping to LP11.
Add configuration of the mode via V4L2_MBUS_CSI2_NONCONTINUOUS_CLOCK.

With a read only control there is limited point in advertising
a minimum and maximum for the control, so change to set the
value, min, and max all to the selected pixel rate.

With the binned modes, there is little point in faithfully
reproducing the horizontal line length of 5352 pixels on the CSI2
bus, and the FIFO between the pixel array and MIPI serialiser
allows us to remove that dependency.
Allow the pixel array to run with the normal settings, with the MIPI
serialiser at half the rate. This requires some additional
information for the link frequency to pixel rate function that
needs to be added to the configuration tables.

This is a v1 with my ack, something has gone awry here. It's also
missing your signoff. Did you pick up someone else's series?

Yes, this is a continuation of Dave's work. I contacted him directly,
and he mentioned that he is unable to submit a v2 any time soon and
was open to someone else continuing it in his stead. This is my first
time submitting a patch via a mailing list, so I'm not sure if I'm
missing something, but I only added my sign off for anything that
actually included work from my side and not just bringing his patch
forward to this patch series.

Yes, this is a continuation of Dave's work. I contacted him directly,
and he mentioned that he is unable to submit a v2 any time soon and
was open to someone else continuing it in his stead. This is my first
time submitting a patch via a mailing list, so I'm not sure if I'm
missing something, but I only added my sign off for anything that
actually included work from my side and not just bringing his patch
forward to this patch series.

Your cover letter states v2, but the individual patches do not.
Add the '-v2' (or, rather, next it will be '-v3') to git format-patch
when you save your series and it will add the version to each patch. You
can also add '-s' to that command I believe to add your SoB to each
patch.

Ah okay. Unfortunately I see so many binding patches pass by that I
sometimes forget about what I already reviewed, and I did not
remember this one at all.

Right. The rules are that you need to add it when you send someone's
work, like chain of custody type of thing.

No worries I'm not surprised since i see constant things submitted
to upstream and v1 was actually sent a year ago so there would be no
shot that i would remember it either.

There are a number of variants of the imx258 modules that can not
be differentiated at runtime, so add compatible strings for them.

Two people working on patch but no one tested it before sending. Do not
send untested code.
It does not look like you tested the bindings, at least after quick
look. Please run `make dt_binding_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).
Maybe you need to update your dtschema and yamllint.
Best regards,
Krzysztof

Hello, looks like I messed this up during my v2 (sorry missed the v in
my format patch) when I took this off Dave's hands. This is all new to
me so thank you for the command used to check, I was only compiling
the kernel and testing that so I didn't realize this needed separate
testing.
Looks like it no longer complains when i run
make dt_binding_check DT_SCHEMA_FILES=media/i2c/sony,imx258
with the following
properties:
compatible:
enum:
- sony,imx258
- sony,imx258-pdaf
If that looks good I can go ahead and include that in the v3

But you are only adding 1 variant.

That's more reasoning/why for the patch than description of the h/w.

How do I know which one to use? Please define what PDAF means somewhere
as well as perhaps what the original/default variant is or isn't.

I can not speak for Dave but as to why this was added here but looking
at the imx296 yaml that has something similar where there are multiple
variants that may not be detectable at run time but does not include
similar verbiage in the main description. Should I drop this from the
description so it matches the imx296?

Would it make sense to change the properties to include a description like so
properties:
compatible:
enum:
- sony,imx258
- sony,imx258-pdaf
description:
The IMX258 sensor exists in two different models, a standard variant
(IMX258) and a variant with phase detection autofocus (IMX258-PDAF).
The camera module does not expose the model through registers, so the
exact model needs to be specified.

Just change "add compatible strings for them" to "add compatible string
for the PDAF variant" or something.

Ohh i see what you mean now, this is in reference to the commit message,
it was throwing me off because the imx258 description had almost the
exact same wording. Yes that makes sense, ill change the commit
message to specify PDAF.

Ohh i see what you mean now, this is in reference to the commit message,
it was throwing me off because the imx258 description had almost the
exact same wording. Yes that makes sense, ill change the commit
message to specify PDAF.

* [PATCH 19/23] media: i2c: imx258: Change register settings for variants of the sensor

From: Dave Stevenson <dave.stevenson@raspberrypi.com>
Sony have advised that there are variants of the IMX258 sensor which
require slightly different register configuration to the mainline
imx258 driver defaults.
There is no available run-time detection for the variant, so add
configuration via the DT compatible string.
The Vision Components imx258 module supports PDAF, so add the
register differences for that variant

From: Dave Stevenson <dave.stevenson@raspberrypi.com>
Sony have advised that there are variants of the IMX258 sensor which
require slightly different register configuration to the mainline
imx258 driver defaults.
There is no available run-time detection for the variant, so add
configuration via the DT compatible string.
The Vision Components imx258 module supports PDAF, so add the
register differences for that variant

From: Dave Stevenson <dave.stevenson@raspberrypi.com>
The sensor supports H & V flips, but the controls were READ_ONLY.
Note that the Bayer order changes with these flips, therefore
they set the V4L2_CTRL_FLAG_MODIFY_LAYOUT property.

Ok ill create separate patch for adding in the binding and then
a follow up patch with the other half that actually adds it to
