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 ?
I have hardware to verify it on i.MX8MM but from exynos I don't have any contact from Samsung to suggest or test. Maybe I can add Tomasz Figa while sending the changes?
Tomasz hasn't been working for Samsung for a loooong time (I've dropped his Samsung address from the CC list for this reason).
Okay. I think exynos drm maintainers might help out here, but not sure of it.
I understand that there are 2 key implementations.
- Adjust the exynos_drm_dsi.c by dropping component_ops as i.MX8MM
flow with LCDIF doesn't have component_ops (make sure it works with exynos platform first)
I think it should be turned into a real drm_bridge, it's currently implemented based on drm_encoder.
Yes, ie what I'm trying for.
