[PATCH v2 1/4] media/v4l2-core: Add enum V4L2_FWNODE_BUS_TYPE_DPI

[PATCH v2 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.

Tested-by: Chen-Yu Tsai <wenst@chromium.org>

Confirmed this fixes the display on Juniper (Acer Chromebook Spin 311) on
mainline (next-20220422).

Xin, in the future, please send the whole series to all recipients of
all patches listed by get_maintainers.pl, not just the recipients of
each patch. In the case of this series, they should have been sent
to all of the mailing lists (media, devicetree, dri-devel) so that
everyone has the same, full view of the patches.

Forgot to mention, this device uses the already supported but broken (by
previous DPI patch) DSI interface.

Marek says the prerequisite landed through linux-media, and that's why
it compilers on linux-next but not in drm-misc-next.

Don't do that.

Instead:
- merge all patches through one branch, with the foreign patches acked
for that merge patch
- wait until you can backmerge all the dependencies
- do a topic branch

This probably needs to be reverted here and instead merged through
linux-media. Or you wait until -rc1 and then apply it to
drm-misc-next.

Hi Daniel, I use git send-email to upstream patch and automatically
generated reviewer list, so patch 1/4 and 2/4 send to linux-media, and
these 2 patches already merged in linux-media.

This is one of the reasons why you should always send the "full" series
to all recipients. That way people, especially maintainers, are more
likely to notice build time cross tree dependencies like this one, and
work towards a common resolution.
