[RFC PATCH 00/17] drm: bridge: Samsung MIPI DSIM bridge

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This series supports common bridge support for Samsung MIPI DSIM
which is used in Exynos and i.MX8MM SoC's.

The final bridge supports both the Exynos and i.MX8MM DSI devices.

Right now bridge offers two sets of implementations.

A. With component_ops and exynos specific code exclusively for
   exynos dsi drivers and it's legacy bindings.

B. Without componenet_ops for newly implemented bridges and its
   users like i.MX8MM.

The future plan is to fix the implementation A) by dropping
component_ops and fixing exynos specific code in order to make
the bridge more mature to use and the same is mentioned in
drivers TODO.

Patch 0001 - 0006: Bridge conversion
Patch 0007 - 0017: Samsung MIPI DSIM bridge fixes, additions

Tested in Engicam i.Core MX8M Mini SoM.

Anyone interest, please have a look on this repo
https://github.com/openedev/linux/tree/070421-imx8mm-dsim

Would appreciate anyone from the exynos team to test it on
the exynos platform?

Any inputs?
Jagan.
