Jagan,

Thanks - I was able to get this series working using the set of
exynos/drm patches from Michael submitted back in 2020-09-11:
https://patchwork.kernel.org/project/dri-devel/list/?series=347439&archive=both&state=*

This exynos/drm RFC series you posted back in July was where I
recalled the discussion about if the exynos driver could be split up
vs duplicating parts of it in a separate driver.

There were also some comments about this series. Can you address those
comments, rebase and resend?

I have not been able to get my hardware to work with this series yet
and am still debugging that (currently crashing in
samsung_dsim_host_attach)

This was originally from Marek submitted on Oct 3 2020: [PATCH] phy:
exynos-mipi-video: Add support for NXP i.MX8MM

This one seems to have been acked but never got picked up for some reason.

Marek, can you add the tags and re-submit?
