Looking at the register set, it seems to match the Exynos 5433,
supported by drivers/gpu/drm/exynos/exynos_drm_dsi.c. Can we leverage
that driver instead of adding a new one for the same IP core ?

Yes. there was an attempt from Michael in this direction:
https://patchwork.kernel.org/project/dri-devel/cover/20200911135413.3654800-1-m.tretter@pengutronix.de/

Thanks for the reference, I will check it out and see I can send any
updated versions wrt my i.MX8MM platform.

Thanks.

I had a brief look at the exynos driver, and I think it should be turned
into a DRM bridge as part of this rework to be used with the i.MX8MM.

Is there someone from Samsung who could assist, at least to test the
changes ?

Yes, I mentioned few guys in reply to PHY. Around the DRM drivers you
can get in touch with:

Seung-Woo Kim [off-list ref]
Marek Szyprowski [off-list ref]
Andrzej Hajda [off-list ref]

The easiest testing of the display stack would be on Hardkernel's Odroid
XU4 (https://www.hardkernel.com/shop/odroid-xu4-special-price/) however
you will not test the DSI/DSIM directly (it has only HDMI port).

Best regards,
