This series support MIPI DSI on i.MX8MM.
The DSIM bridge still need to work to make it compatible for exynos drm dsi hardware block.
This series work directly on to of linux-next with recent dispmix-blk-ctrl changes.
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&archi...
Tested on i.Core MX8M Mini SoM with EDIMM2.2 and CTOUCH2 Carrier boards.
Required changes:
- DSIM driver

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.
Not sure Laurent, Inki has some discussion about this [1], looks like they are still looking for a common 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)
I've initially tried a separate driver instead of exynos.[2]
- DPHY change
This was originally from Marek submitted on Oct 3 2020: [PATCH] phy: exynos-mipi-video: Add support for NXP i.MX8MM
I'm thinking this may not be required, as dphy reset can now handle via blk-ctrl like this [3]. I have tested the reset handling via blk-ctrl and it works for me.
This one seems to have been acked but never got picked up for some reason.
Marek, can you add the tags and re-submit?
- Bus format fix

Jagan, can you submit this?
This is indeed not required, drm handles the bridge state via atomic API's. I did check that as well. I will link my latest series soon.
