Hello,

This small patch series is the result of me getting a bus-type numerical
value wrong in a device tree file and spending too long debugging the
issue. Hopefully there's nothing controversial here.

Compared to v1, the PARALLEL bus type has been renamed to BT601, and
patch 3/3 now converts existing DT sources. See individual patches for a
detailed changelog.

I can split patch 3/3 per architecture or per board if desired, but
given that this is a mechanical change, and the patch is fairly small,
I'd rather keep it as-is and merge it as part of the series.

When writing 3/3 I noticed that the anx7625 bindings and the
corresponding driver badly misuse the bus type (mapping CCP2 to mean
MIPI DPI, and PARALLEL - now BT601 - to mean MIPI DSI). This misuse
hasn't reached a released mainline kernel as it got merged in v5.17-rc1,
so there may still be a chance to fix it. Let's discuss this in [1],
I'll update this series and rebase it on v5.18-rc1 once released based
on the outcome of the discussion.

Add a new dt-bindings/media/video-interfaces.h header that defines
macros corresponding to the bus types from media/video-interfaces.yaml.
This allows avoiding hardcoded constants in device tree sources.

Now that a header exists with macros for the media interface bus-type
values, replace hardcoding numerical constants with the corresponding
macros in the DT binding examples.

* [PATCH v2 2/3] dt-bindings: Use new video interface bus type macros in examples
@ 2022-03-06 17:39   ` Laurent Pinchart

From: Laurent Pinchart @ 2022-03-06 17:39 UTC (permalink / raw)

  Cc: Jacopo Mondi, Maxime Coquelin, Hugues Fruchet, Alexandre Torgue,
	Shawn Guo, Lad Prabhakar, Rob Herring, Sakari Ailus,
	Eugen Hristev, linux-arm-kernel

Now that a header exists with macros for the media interface bus-type
values, replace hardcoding numerical constants with the corresponding
macros in the DT binding examples.

Now that a header exists with macros for the media interface bus-type
values, replace hardcoding numerical constants with the corresponding
macros in the DT sources.

Contrary to popular belief, further investigation revealed that BT.601
doesn't define VSYNC and HSYNC (or HREF, as it is also commonly called)
signals. MEDIA_BUS_TYPE_BT601 is thus likely not a good name. I haven't
been able to find a standard for parallel camera interfaces that would
be a good match here. On the display side there's MIPI DPI, but on the
camera side it seems things have evolved quite organically. I may have
missed something though.

So keep 'PARALLEL' and anything less ambiguous will be a new type.

sorry for this late answer. Is it possible to split ARM DT patches by 
vendor ?
