drm/rcar-du: Introduce CRTCs groups 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.

drm/rcar-du: Support per-CRTC clock and IRQ Some of the DU revisions use one clock and IRQ per CRTC instead of one clock and IRQ per device. Retrieve the correct clock and register the correct IRQ for each CRTC. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

drm: rcar-du: Add support for external pixel clock The DU uses the module functional clock as the default pixel clock, but supports using an externally supplied pixel clock instead. Support this by adding the external pixel clock to the DT bindings, and selecting the clock automatically at runtime based on the requested mode pixel frequency. The input clock pins to DU channels routing is configurable, but currently hardcoded to connect input clock i to channel i. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

drm/rcar-du: Rework output routing support 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>
