Hello everyone, The dt-binding added in this series depends on [1] for "make dt_binding_check" to pass. The biggest change in v8 is a conversion of the imx6 host controller driver to drm_bridge and an extension to dw_mipi_dsi.c which allows platform drivers to daisy-chain bridges between the encoder and the Synopsis DSI bridge. Obviously a lot more work can be done on this front, for example to convert the Rockchip and STM platform drivers to drm_bridge (the STM driver doesn't even use the current dw_mipi_dsi.c bind API to attach) or to improve the API itself. Another kind of related work is refactoring the existng IMX drivers to drm_bridge and move the empty encoder management to imx-drm-core. Because this patch is already quite big, I did only the minimum changes to get the imx6 mipi dsi driver in good shape, all the other changes should be done in separate patch series. I also just realized imx6qdl.dtsi was missing some properties to get the DSI host controller working so I've added them as a new patch. All received feedback up to this point has been addressed.
