Hello,
This patch series documents and implements DT bindings support for the R-Car Display Unit (DU).
Unlike the previous attempt that tried to create a new model for composite display devices and failed to get any real traction from DRM developers, the approach taken here focuses on DT bindings without requiring core changes outside of the DU driver.
Aside of the usual boring core properties (compatible, reg, interrupts and clocks), the proposed bindings use the OF graph bindings to model connections between the DU output video ports and the on-board and off-board components. As such they do not depend on any particular implementation or implementation philosophy.
The series starts by documenting DT bindings for the devices present on the Marzen, Lager and Koelsch boards not already supported in the mainline kernel (01/16 to 05/16) and for the DU (06/16). It then reworks the rcar_du platform data to ease implementation of the DT bindings (07/16). The next step is to implement support for the DU DT bindings in the R-Car DU DRM driver (08/16). Finally the remaining patches add the DU DT nodes for all supported SoCs (09/16 to 11/16), remove DU platform data from the DT-based board files (12/16 and 13/16) and describe the on-board devices connected to the DU outputs for the Marzen, Lager and Koelsch boards (14/16 to 16/16).
