As pointed by checkpatch:

	WARNING: DT compatible string "nvidia,tegra210-csi" appears un-documented -- check ./Documentation/devicetree/bindings/
	#628: FILE: drivers/staging/media/tegra-video/csi.c:521:
	+	{ .compatible = "nvidia,tegra210-csi", .data = &tegra210_csi_soc },

	WARNING: DT compatible string "nvidia,tegra210-csi" appears un-documented -- check ./Documentation/devicetree/bindings/
	#3238: FILE: drivers/staging/media/tegra-video/video.c:106:
	+	{ .compatible = "nvidia,tegra210-csi", },

and double-checked with:

	$ git grep "nvidia,tegra210-csi"
	drivers/staging/media/tegra-video/csi.c:        { .compatible = "nvidia,tegra210-csi", .data = &tegra210_csi_soc },
	drivers/staging/media/tegra-video/video.c:      { .compatible = "nvidia,tegra210-csi", },

The DT specs for this driver are missing. I even checked at linux-next:
there's no DT bindings for this.

While the code sounds ok, I'll reject this PR. Please submit a new one
together with the DT file properly reviewed by DT maintainers.

Thanks,
Mauro

Sorry, I should have mentioned this in the cover letter: the binding file
is here: https://patchwork.linuxtv.org/patch/63576/

But it will be merged via the tegra subsystem (Thierry Reding) since it is
part of the display bindings, not media bindings. Also, Thierry was planning
to convert it to yaml, so he offered to merge it instead.

Ok. Please re-send the pull request (or just mark it as New on patchwork) 
once the bindings arrive linux-next.

Alternatively, I don't mind if those patches would also be merged via
Tegra's tree, together with the bindings. On such case, feel free to 
add, for both patches:

It's still marked as New in patchwork :-) (https://patchwork.linuxtv.org/patch/63596/)

Thierry, let us know what you want to do. It might not be a bad idea to merge
the whole series through your tree, as Mauro suggested. It keeps everything
together.

Mauro, do you mind if I turn that into an Acked-by? I think the ARM SoC
maintainers may prefer that as being more of an explicit statement than
Reviewed-by: that it's fine to take this through ARM SoC.

I can do that. For ARM SoC I typically create a for-X.Y/dt-bindings
branch where I collect device tree bindings patches that don't have
a better place anywhere else, so I'll probably stick the DT binding
update into that branch and then I can base a for-5.8/media branch
on top of that to resolve the checkpatch warnings.

Actually, once I have that I could even just send a PR to Mauro to
take this through the media tree since the dependencies should all
be resolved. But with an Acked-by I'm sure the ARM SoC maintainers
won't mind picking this up.

Sure, go ahead.

Whatever works best. I don't mind to either pick it together with
the DT, or to merge it via some other tree with either my
acked-by or reviewed-by.

[GIT PULL FOR v5.8] Add Tegra210 Video input driver

[Hans Verkuil]

Hi Mauro,

This adds the Tegra video input driver. It currently only supports the test
pattern generator, the next phase will add sensor support.

Sowjanya, thank you for all your hard work on this driver!

Regards,

	Hans

PS: The dt-bindings patch https://patchwork.linuxtv.org/patch/63331 will go through
Thierry, together with other non-media patches. The bindings for this device are a
bit unusual since they are under bindings/display due to the HW design.
