2013-08-09drm/rcar-du: Configure RGB output routing to DPAD0Laurent Pinchart
The R8A7790 DU variant has a single RGB output called DPAD0 that can be fed with the output of DU0, DU1 or DU2. Making the routing configurable. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2013-08-09drm/rcar-du: Rework output routing supportLaurent Pinchart
Split the output routing specification between SoC-internal data, specified in the rcar_du_device_info structure, and board data, passed through platform data. The DU has 5 possible outputs (DPAD0/1, LVDS0/1, TCON). SoC-internal output routing data specify which output are valid, which CRTCs can be connected to the valid outputs, and the type of in-SoC encoder for the output. Platform data then specifies external encoders and the output they are connected to. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2013-08-09drm/rcar-du: Add support for DEFR8 registerLaurent Pinchart
The R8A7790 DU has a new extended function control register. Support it. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2013-08-09drm/rcar-du: Add support for multiple groupsLaurent Pinchart
The R8A7790 DU has 3 CRTCs, split in two groups. Support them. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2013-08-09drm/rcar-du: Move output routing configuration to groupLaurent Pinchart
Output routing is configured in group registers, move the corresponding code from rcar_du_crtc.c to rcar_du_group.c. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2013-08-09drm/rcar-du: Introduce CRTCs groupsLaurent Pinchart
The R8A7779 DU is split in per-CRTC resources (scan-out engine, blending unit, timings generator, ...) and device-global resources (start/stop control, planes, ...) shared between the two CRTCs. The R8A7790 introduced a third CRTC with its own set of global resources This would be modeled as two separate DU device instances if it wasn't for a handful or resources that are shared between the three CRTCs (mostly related to input and output routing). For this reason the R8A7790 DU must be modeled as a single device with three CRTCs, two sets of "semi-global" resources, and a few device-global resources. Introduce a new rcar_du_group driver-specific object, without any real counterpart in the DU documentation, that models those semi-global resources.
