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-...
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: Inki Dae inki.dae@samsung.com Seung-Woo Kim sw0312.kim@samsung.com Marek Szyprowski m.szyprowski@samsung.com Andrzej Hajda a.hajda@samsung.com
Thanks for the information.
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).
Look like I found one board with Exynos5430 with DSI. Does this SoC is same as mainline Exynos5433?
Jagan.
