This is v2 of the series to convert the Exynos MIPI DSI driver into a drm bridge and make it usable with other drivers. Although the driver is converted, it still supports the component framework API to stay compliant with the Exynos DRM driver. The Exynos MIPI DSI Phy is also found on the i.MX8M Mini. However, on the i.MX8M Mini, the bridge is driven by an LCDIF display controller instead of the Exynos Decon. The driver for the LCDIF does not use the component framework, but uses drm bridges. I don't have any Exynos SoC to actually test the series. I build a dummy to test the bridge with a component driver, to make sure that at least the initialization is working. Furthermore, tested the driver as a bridge with a few additional unfinished patches on the i.MX8M Mini EVK. However, somebody should verify that the driver is still working on Exynos hardware. I also changed the order of the patches to first make the driver more platform independent (patches 2 to 8), then convert to a drm bridge driver (patches 10 to 13) and finally expose the API, split the code and move the platform independent driver to the bridges (patches 14 - 16). Hopefully this simplifies testing/bisecting and helps me to understand potential error reports. Also I added host_ops for attach/detach and the tearing effect handler to make the calls into the platform code more visible. Furthermore, the series should now apply to linux-next and correctly build the exynos_defconfig.
