The Pixel Pipeline (PXP) is a memory-to-memory graphics processing
engine that supports scaling, colorspace conversion, alpha blending,
rotation, and pixel conversion via lookup table. Different versions are
present on various i.MX SoCs from i.MX23 to i.MX7. The latest versions
on i.MX6ULL and i.MX7D have grown an additional pipeline for dithering
and e-ink update processing that is ignored by this driver.
This series adds a V4L2 mem-to-mem scaler/CSC driver for the PXP version
found on i.MX6ULL SoCs which is a size reduced variant of the i.MX7 PXP.
The driver uses only the legacy pipeline, so it should be reasonably
easy to extend it to work with the older PXP versions found on i.MX6UL,
i.MX6SX, i.MX6SL, i.MX28, and i.MX23. The driver supports scaling and
colorspace conversion. There is currently no support for rotation,
alpha-blending, and the LUTs.
Changes since v1:
- fix node address order in imx6ul.dtsi
- add Rec.709, BT.2020, and SMPTE 240m YCbCr encoding coefficients,
list quantization errors in comments
- split ycbcr_enc and quantization into per-queue configuration,
use default encoding and quantization on capture queue
- replace strncpy with strlcpy
- use struct video_device .device_caps
- remove buffer count reduction, reqbufs will just -ENOMEM if there's not
enough memory
- register video device after m2m init
- disable clocks on failed probe
- remove superfluous whitespace
- fix YUV32 depth
- rename vidioc_* functions to pxp_*
- keep default colorimetry when set
- force ycbcr_enc and quantization to be equal for CSC bypass (RGB<->RGB
and YUV<->YUV conversions)

Add a V4L2 mem-to-mem scaler/CSC driver for the Pixel Pipeline (PXP)
version found on i.MX6ULL SoCs. A similar variant is used on i.MX7D.
Since this driver only uses the legacy pipeline, it should be reasonably
easy to extend it to work with the older PXP versions found on i.MX6UL,
i.MX6SX, i.MX6SL, i.MX28, and i.MX23.
The driver supports scaling and colorspace conversion. There is
currently no support for rotation, alpha-blending, and the LUTs.

Changes since v1:
- add Rec.709, BT.2020, and SMPTE 240m YCbCr encoding coefficients,
list quantization errors in comments
- split ycbcr_enc and quantization into per-queue configuration,
use default encoding and quantization on capture queue
- replace strncpy with strlcpy
- use struct video_device .device_caps
- remove buffer count reduction, reqbufs will just -ENOMEM if there's not
enough memory
- register video device after m2m init
- disable clocks on failed probe
- remove superfluous whitespace
- fix YUV32 depth
- rename vidioc_* functions to pxp_*
- keep default colorimetry when set
- force ycbcr_enc and quantization to be equal for CSC bypass (RGB<->RGB
and YUV<->YUV conversions)

That way if userspace sets
V4L2_XFER_FUNC_DEFAULT
V4L2_YCBCR_ENC_DEFAULT
V4L2_QUANTIZATION_DEFAULT
on the output queue, it will get
V4L2_XFER_FUNC_DEFAULT
V4L2_YCBCR_ENC_DEFAULT
V4L2_QUANTIZATION_DEFAULT
on the capture queue.
If userspace sets xfer_func explicitly, it will get the explicit default
ycbcr_enc and quantization values.
I think I did this to make v4l2-compliance at some point, but it could
be that the explicit output->capture colorimetry copy for RGB->RGB and
YUV->YUV conversions has me covered now.

please correct me if i'm wrong, but the driver in patch #3 only support imx6ull so this binding is misleading. As a user i would expect that binding and driver are in sync.

please correct me if i'm wrong, but the driver in patch #3 only support imx6ull so this binding is misleading. As a user i would expect that binding and driver are in sync.

This xfer_func test makes no sense. xfer_func is completely ignored by the
driver (other than copying it from output to capture queue) since it can't
make any changes to it anyway.
What you are trying to do in pxp_fixup_colorimetry() is to figure out the
ycbcr_enc and quantization values for the capture queue.
BTW, can you rename pxp_fixup_colorimetry to pxp_fixup_colorimetry_cap or
something? Since it is specifically for the capture queue.
These values depend entirely on the capture queue pixelformat and on the
colorspace and not on the xfer_func value.
So just do:
bool is_rgb = !pxp_v4l2_pix_fmt_is_yuv(dst_fourcc);
*ycbcr_enc = V4L2_MAP_YCBCR_ENC_DEFAULT(ctx->colorspace);
*quantization = V4L2_MAP_QUANTIZATION_DEFAULT(is_rgb, ctx->colorspace,
*ycbcr_enc);
BTW, I just noticed that the V4L2_MAP_QUANTIZATION_DEFAULT macro no longer
uses ycbcr_enc. The comment in videodev2.h should be updated. I can't
change the define as it is used in applications (and we might need to
depend on it again in the future anyway).
If this code will give you v4l2-compliance issues, please let me know.
It shouldn't AFAICT.

Yes. I checked again without that. Since there is the forced out->cap
copy for RGB->RGB and YUV->YUV conversions in pxp_fixup_colorimetry,
v4l2-compliance is happy anyway. The pxp_default_quant/ycbcr_enc
functions are removed now.

That's almost exactly what I ended up with, thank you.

That is correct.
I assume it should work on i.MX7D mostly unchanged, by just adding a
compatible. The others probably require some register layout changes.

I disagree. The binding document specifies how PXP hardware should be
described in the device tree. It should be seen completely separate from
any driver implementation.
There is no reason to leave out SoCs that are known to contain the PXP
from this description just because some driver doesn't implement support
for them. Similarly, there is no reason to remove the second interrupt
just because the current Linux driver doesn't use it.
> As a user i would expect that binding and driver are in sync.
This expectation is at odds with the purpose of DT bindings, which is to
describe the hardware, not to document driver features.
(Which driver, anyway? Drivers for other operating systems or
bootloaders could have a different set of supported SoCs and features).
