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.MX8M Mini/Nano/Plus.

Changes for v8:
* fixed comment lines
* fixed commit messages
* fixed video mode bits
* collect Marek Ack
* fixed video mode bit names
* update input formats logic
* added imx8mplus support

Changes for v7:
* fix the drm bridge attach chain for exynos drm dsi driver
* fix the hw_type checking logic

Changes for v6:
* handle previous bridge for exynos dsi while attaching bridge 

Changes for v5:
* bridge changes to support multi-arch
* updated and clear commit messages
* add hw_type via plat data
* removed unneeded quirk
* rebased on linux-next

Changes for v4:
* include Inki Dae in MAINTAINERS
* remove dsi_driver probe in exynos_drm_drv to support multi-arch build
* update init handling to ensure host init done on first cmd transfer

Changes for v3:
* fix the mult-arch build
* fix dsi host init
* updated commit messages

Changes for v2:
* fix bridge handling
* fix dsi host init
* correct the commit messages

Patch 0001:	Fix MIPI_DSI*_NO_* mode bits

Patch 0002:	Properly name HSA/HBP/HFP/HSE bits

Patch 0003: 	Samsung DSIM bridge

Patch 0004:	PHY optional

Patch 0005:	OF-graph or Child node lookup

Patch 0006: 	DSI host initialization 

Patch 0007:	atomic check

Patch 0008:	PMS_P offset via plat data

Patch 0009:	atomic_get_input_bus_fmts

Patch 0010:	input_bus_flags

Patch 0011:	document fsl,imx8mm-mipi-dsim

Patch 0012:	add i.MX8M Mini/Nano DSIM support

Patch 0013:	document fsl,imx8mp-mipi-dsim

Patch 0014:	add i.MX8M Plus DSIM support

Tested in Engicam i.Core MX8M Mini SoM.

Did you miss to collect all the Tested-by tags from v7, or did you drop
them deliberately?

Few changes in v8 compared to v7, so I've not picked these tags as code changes.

I tested this on the Kontron DL i.MX8MM which uses a TI SN65DSI84 bridge
and a Jenson 7" LVDS Display.
