[PATCH v5 0/6] rcar-vin: Add support for R-Car V4M

[PATCH v5 0/6] rcar-vin: Add support for R-Car V4M

[Niklas Söderlund]

Hello,

This series adds bindings and support to rcar-vin for R-Car V4M by the
means of adding a Gen4 family fallback compatible.

Previous versions of this series added V4M support like done for VIN
since the first Gen3 device, by the use of only a single SoC specific
compatible value. This was done as in Gen3 almost every new device
differed from the others and a family fallback was not very useful.

For the Gen4 devices with a video capture pipeline currently documented 
the VIN instances are very similar and a family fallback can be used.  
This however requires updating existing DTS files to add this new family 
fallback. This is done in a backward compatible way and the driver 
retains the compatible values.

See individual patches for changes since previous versions.

[PATCH v5 1/6] dt-bindings: media: renesas,vin: Add Gen4 family fallback

[Niklas Söderlund]

The Gen4 SoCs V3U, V4H and V4M have a similar video capture pipelines.

The datasheets for the SoCs have small nuances around the Pre-Clip
registers ELPrC and EPPrC in three use-cases, interlaced images,
embedded data and RAW8 input. On V4H the values written to the registers
are based on odd numbers while on V4M they are even numbers, values are
based on the input image size. No board that uses these SoCs which also
have the external peripherals to test these nuances exists. Most likely
this is an issue in the datasheet.

Before adding bindings for V4M add a family compatible fallback for
Gen4. That way the driver only needs to be updated once for Gen4, and we
still have the option to fix any problems in the driver if any testable
differences between the SoCs are found.

There are already DTS files using the V3U and V4H compatibles which
needs to be updated to not produce a warning for DTS checks. The driver
also needs to kept the compatible values to be backward compatible , but
for new Gen4 SoCs such as V4M we can avoid this.

I believe it was requested in earlier comments to use SoC specific
compatible as fallback.

See:
https://lore.kernel.org/all/20240624-rented-danger-300652ab8eeb@wendy/
https://lore.kernel.org/all/20240610-screen-wolverine-78370c66d40f@spud/
https://lore.kernel.org/all/20240620-gating-coherent-af984389b2d7@spud/

You ignored these suggestions and decided to go with other approach.

I don't agree with this.

Please carry:

Nacked-by: Krzysztof Kozlowski <krzk@kernel.org>

so my objection and your avoidance of earlier suggestions will be
clearly documented.

Best regards,
Krzysztof

[PATCH v5 2/6] arm64: dts: renesas: r8a779g0: Add family fallback for VIN IP

[Niklas Söderlund]

To make it easier to support new Gen4 SoCs a family fallback compatible
similar to what is used for Gen2 have been added to the VIN bindings.
Add this fallback to the V4H DTSI.

There is no functional change, but the addition of the family fallback
in the bindings produces warnings for V4H for DTS checks if they are not
added.

[PATCH v5 3/6] arm64: dts: renesas: r8a779a0: Add family fallback for VIN IP

[Niklas Söderlund]

To make it easier to support new Gen4 SoCs a family fallback compatible
similar to what is used for Gen2 have been added to the VIN bindings.
Add this fallback to the V3U DTSI.

There is no functional change, but the addition of the family fallback
in the bindings produces warnings for V3U for DTS checks if they are not
added.

Signed-off-by: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se>

* Changes since v4
- New in v5.

[PATCH v5 4/6] media: rcar-vin: Add family compatible for R-Car Gen4 family

[Niklas Söderlund]

Add the Gen4 family compatible. This will be used instead of a SoC
specific compatible for the new Gen4 SoC V4M. Two Gen4 boards (V3U and
V4H) have already been added prior and their bindings need to be kept
for backward compatibility.

Signed-off-by: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se>
---
* Changes since v4
- Extend to cover V3U as well, which despite the name is the first Gen4
  board.

* Changes since v3
- Reworked to deal with a Gen4 family compatible instead of a V4M SoC
  specific one.
- Dropped review tags.

* Changes since v2
- Extend commit message to explain why SoC specific compatibles are use
  in the driver instead of adding a new Gen4 fallback to cover both V4H
  and V4M.
- Add review tags.

* Changes since v1
- Create a shared Gen4 info structure.

[PATCH v5 6/6] arm64: dts: renesas: r8a779h0: Add family fallback for VIN IP

The usage of the V4M VIN bindings where merged before the bindings where
approved. At that time the family fallback compatible where not part of
the bindings, add them.

Any chance the media parts can be accepted, so I can take the DTS
patches through the Renesas tree?

BTW, running b4 seems to add two bogus Acked-by tags from Conor:

What's happening?

I would be happy to have some feedback on the media parts as well as I 
will need to send a very similar series for the rcar-isp driver to add a 
family fallback for Gen4. But I have hold of on posting them until I 
knew this is the correct path forward.

No idea, I can't find any Acks from Conner in my inbox neither. Both 
patches in question where new in v4 of the series.

I've reviewed the DT and media patches (1/6, 4/6 and 5/6), and will
include them in a pull request later today with the minor typos reproted
in the reviews fixed.
