- 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 doesn't initialize correctly.

Tested on a Pinephone Pro by forcing 24 mhz clock. 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 shouldn't
be a regression.



v1 Dave Stevenson

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.

Subject: [PATCH v5 02/25] media: i2c: imx258: Make image geometry meet sensor requirements

From: Dave Stevenson <[email protected]>

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.

Subject: [PATCH v5 03/25] media: i2c: imx258: Disable digital cropping on binned modes

From: Dave Stevenson <[email protected]>

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.

Subject: [PATCH v5 08/25] media: i2c: imx258: Add support for 24MHz clock

From: Dave Stevenson <[email protected]>

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.

Subject: [PATCH v5 10/25] media: i2c: imx258: Follow normal V4L2 behaviours for clipping exposure

From: Dave Stevenson <[email protected]>

V4L2 sensor drivers 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.

Subject: [PATCH v5 20/25] media: i2c: imx258: Make HFLIP and VFLIP controls writable

From: Dave Stevenson <[email protected]>

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.
