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

Previous v2 can be available here [1].

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

On, summary this patch-set break the entire DSIM driver into
- platform specific glue code for platform ops, component_ops.
- common bridge driver which handle platform glue init and invoke.

Patch 0001:	Restore proper bridge chain in exynos_dsi

Patch 0002: 	Samsung DSIM bridge

Patch 0003:	Common lookup code for OF-graph or child

Patch 0004: 	plat_data quirk flag via driver_data

Patch 0005/11:  bridge fixes, atomic API's

Patch 0012:	document fsl,imx8mm-mipi-dsim

Patch 0013:	add i.MX8MM DSIM support

Tested in Engicam i.Core MX8M Mini SoM.

Anyone interested, please have a look on this repo [2]

You also need:
L: dri-devel@lists.freedesktop.org

and probably also at least Inki Dae as maintainer as well:
M: Inki Dae <inki.dae@samsung.com
