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.
