[PATCH 1/4] media/v4l2-core: Add enum V4L2_FWNODE_BUS_TYPE_DPI

[PATCH 1/4] media/v4l2-core: Add enum V4L2_FWNODE_BUS_TYPE_DPI

[Xin Ji]

As V4L2_FWNODE_BUS_TYPE_PARALLEL is not used for DPI interface, this
patch add V4L2_FWNODE_BUS_TYPE_DPI for video DPI interface.

Changing is an ABI break, but didn't we revert adding this?

Hi Rob, sorry, what do you mean about ABI break? Do I need remove this
patch in this serial? Or do I need revert patch
https://patchwork.freedesktop.org/patch/462331/, I don't know how to do
it.

I contributed to the confusion about this, let's see if we can clear it up.

An issue was found related to which enum values were used to represent
what late in the last release cycle. As a result a revert[1] patch for
everything touching bus-type in anx7625 was merged.

This patch, does not apply to drm-misc-next due to the revert, and if
Xin Ji rebases his work on the drm-misc-next there should be no
ABI-change as this patch when fixed up will introduce bus-type to the
nax7625 ABI.

Xin: Does this make sense to you?

Hi Robert Foss, yes, my work is based on drm-misc-next, all I can do,
just make a fix up patch(this patch) to change the bus-type define.

The revert was applied to the soc tree and merged into Linus's tree
in v5.17-rc8. It was not present in drm-misc-next until April 5 with
commit 9cbbd694a58b ("Merge drm/drm-next into drm-misc-next").

So please fetch the latest drm-misc-next, rebase your patches on top, and
resend.


Thanks

[PATCH 4/4] drm/bridge: anx7625: Use DPI bus type

[Xin Ji]

As V4L2_FWNODE_BUS_TYPE_PARALLEL not properly descript for DPI
interface, this patch use new defined V4L2_FWNODE_BUS_TYPE_DPI for it.

Fixes: fd0310b6fe7d ("drm/bridge: anx7625: add MIPI DPI input feature")
