Hi all
This series adds support for the Microchip SAMA5D4 VPU, which it based
on the Hantro G1.
The hardware can support up-to 1280x720 for each of the MPEG2, VP8 and
H264 codecs. There is only a single decoder and no encoders on the SoC.
The Hantro G1 post-processing is also enabled on the platform.
To minimise duplication, the series starts with a few small cleanups.
As you may have noticed, this is my first patches series to linux-media,
so any tips how to make this as smoother process are appreciated.
Changes in v2:
- Add testing results in the cover letter (thanks Eze)
- s/Atmel/Microchip/ through the series (thanks Nicolas)
- Split defconfig change into separate commit (thanks Eze, Nicolas)
- Added Reviewed-by and Fixes tags (thanks Philipp)
- Split DT into separate commit, wrote binding document, fixup minor DT
warnings (thanks Eze)
- Rebased on top of 5.12-rc2, as per Linus' email to avoid 5.12-rc1

Confirmed the VPU is used by observing the interrupts triggering, strace
showed extra v4l2 ioctls - VIDIOC_S_FMT(... V4L2_PIX_FMT_YUYV ...)

Confirmed the VPU is used by observing the interrupts triggering, strace
showed the v4l2 ioctls being used plus played back the resulting file.
- VP8 testing, using fluster
Command used:
fluster.py run -ts VP8-TEST-VECTORS -d GStreamer-VP8-V4L2SL-Gst1.0

Use the register directly over the existing SWREG().
Ideally we'll port the driver away from the local registers, but for
now this is enough. For context - I was reading through the IRQ register
handling across the variants.

The current imx8 code does not use the jpeg encoder. Remove the

The SoC features a Hantro G1 compatible engine. Enable it by default, so
people can make use of it.
Keep it a module, as suggested by Nicolas

Do you have any input of the patches or series as a whole?
If you prefer we can drop the last two patches for the defconfig. I've
included those for posterity.
Thanks for the review Eze.
Would you recommend that I resend the series with your R-B or it's
better to wait for feedback from others?

The patch series looks good to me.
If needed on patches that we don't take ourselves, you can add my:
Acked-by: Nicolas Ferre <nicolas.ferre@microchip.com>
Now, when we have the tag from Rob, how to coordinate these different
pieces? Will it go through the media git tree? Will we benefit from a
stable branch to share or will we just have to wait for the driver to
hit Mainline before adding the defconfig and DT patches?

No strong opinion on my side, except that defconfig stuff might be
better handled in at91 + arm-soc trees because we'll have other changes
to queue for 5.13.

The patch series looks good to me.
If needed on patches that we don't take ourselves, you can add my:
Acked-by: Nicolas Ferre <nicolas.ferre@microchip.com>
Now, when we have the tag from Rob, how to coordinate these different
pieces? Will it go through the media git tree? Will we benefit from a
stable branch to share or will we just have to wait for the driver to
hit Mainline before adding the defconfig and DT patches?

No strong opinion on my side, except that defconfig stuff might be
better handled in at91 + arm-soc trees because we'll have other changes
to queue for 5.13.

Thanks a lot for this nice work. Best regards,

Why do you need a name? *-names are used to distinguish multiple entries

I think the defconfig and dt patches can go through at91 as soon as we
get Rob's ack. There is no build dependency so it can be taken at any
time. Worst case, we end up with a selected config option that doesn't
exist.

I think the defconfig and dt patches can go through at91 as soon as we
get Rob's ack. There is no build dependency so it can be taken at any
time. Worst case, we end up with a selected config option that doesn't
exist.

On one hand the names are used to describe the hardware - the SAMA
board uses designated clock and interrupt lines - both called "vdec".
Additionally the names are ultimately required by the underlying API -
platform_get_irq_byname and devm_clk_bulk_get respectively.
How can we get the respective entries without the name?
Skimming through the existing dts file -
arch/arm/boot/dts/sama5d4.dtsi and other dts files - there are lots of
examples where the device tree binding contains the name for a single
clock/interrupt.

My personal preference is to merge everything in one go.
I believe it will be easier from maintainer's point of view, plus odds
of conflicts with the AT91 tree are close to zero.
Then again, as long as the maintainers are happy - I'm fine either way.

Agreed, and it simplify things.
My only concern is with triggering some of the bots while checking for
DT compatible string definition.

There are APIs to get the resource by index as opposed to by name.
E.g. platform_get_irq.
However, you are confusing here internal kernel implementation
with devicetree bindings. The latter is just a representation
of the hardware.

And even if you find examples, the fact that there exist examples
doesn't mean it's the right thing to do.

I guess you are right.
I was about to argue that it makes backwards compatibility easier,
but I suspect that's not the case either.

Indeed, "core" might be a better choice. But it seems we don't need
names here.

I'm taking defconfig 2 last patches of your series right now. No need to
include them in subsequent versions.
For DT, I'm waiting for settlement on refined code. As indicated by
Alexandre, changes will need to travel through arm-soc tree so we'll
coordinate when patches are ready.
Thanks a lot! Best regards,
Nicolas

My train of thought was that if we're missing API to fetch the entries
via non-name means, then there's a reasonable precedent to expose the
name. Clearly I missed the API, so my argument is just off.
