Hi Dave and Daniel,
Just one patch series that moves the existing Exynos DSI driver
to drm/bridge directory to support both SoCs family - Exynos
and I.MX - because same Exynos MIPI DSI ip can be used by the two
different SoC family.
Of course, there are some concerns about this patch series because Exynos
and I.MX SoCs have different HW characteristic but use the same HW driver.
However, I believe that there should be no problem as Exynos and I.MX
developers have conducted tests and reviews enough for about a year
since last April.
This would be the first case that we allow different vendor SoCs to use
same device driver at least in DRM world so we anticipate experiencing
and resolving new issues through ongoing maintenance, and ultimately,
the experiences gained here will undoubtedly be able to contribute
the development of the community as well.
Please kindly let me know if there is any problem.
Thanks,
Inki Dae

drm: bridge: samsung-dsim: Add i.MX8M Plus support (2023-03-28 09:05:41 +0900)
----------------------------------------------------------------
A patch series for moving MIPI-DSI driver for Exynos DRM to drm/bridge
directory so that I.MX SoC family can also share the same device driver.
Samsung MIPI DSIM device is a common IP that can be used by Exynos and I.MX8M
Mini/Nano/Plus SoC. Regarding this, this patch series has added several
things below to existing MIPI DSI driver,
- Add exynos_dsi_type enum type to provide controller data from different
platforms.
- Add two pipeline detection ways support - existing Exynos DSI child node
and I.MX family of-graph port or ports.
- Consider component and bridged based DRM drivers.
- Add device tree binding support of I.MX family.
