2013-08-10drm/rcar-du: Add FBDEV emulation supportLaurent Pinchart1-8/+28
Use the FB CMA helpers to implement FBDEV emulation support. The VGA connector status must be reported as connector_status_connected instead of connector_status_unknown to be usable by the emulation layer. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2013-08-10drm/rcar-du: Add internal LVDS encoder supportLaurent Pinchart1-0/+5
The R8A7790 includes two internal LVDS encoders. Support them in the DU driver. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2013-08-10drm/rcar-du: Rework output routing supportLaurent Pinchart1-6/+11
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>
2013-08-10drm/rcar-du: Add support for multiple groupsLaurent Pinchart1-12/+31
The R8A7790 DU has 3 CRTCs, split in two groups. Support them. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2013-08-10drm/rcar-du: Fix buffer pitch alignment for R8A7790 DULaurent Pinchart1-3/+14
The R8A7790 DU seems to require a 128 bytes pitch alignment, even though the documentation only mentions a 16 pixels alignement as for the R8A7779 DU. Make this configurable through a device flag. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2013-08-10drm/rcar-du: Use dynamic number of CRTCs instead of CRTCs array sizeLaurent Pinchart1-1/+1
The rcar_du_device structure contains a field that stores the number of CRTCs, use it instead of the CRTCs array size. This prepares the driver to support a variable number of CRTCs. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2013-08-10drm/rcar-du: Introduce CRTCs groupsLaurent Pinchart1-4/+7
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.

2013-08-10drm/rcar-du: Rename rcar_du_plane_(init|register) to rcar_du_planes_*Laurent Pinchart1-2/+2
The functions initialize or register all planes, rename them accordingly. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2013-08-10drm/rcar-du: Rename platform data fields to match what they describeLaurent Pinchart1-3/+2
The struct rcar_du_encoder_data encoder::field describes the encoder type, and the rcar_du_encoder_lvds_data and rcar_du_encoder_vga_data structures describe connector properties. Rename them accordingly. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2013-08-10drm/rcar-du: Merge LVDS and VGA encoder codeLaurent Pinchart1-43/+6
Create a single rcar_du_encoder structure that implements a KMS encoder. The current implementation is straightforward and only configures CRTC output routing. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2013-07-05drm/rcar-du: Fix buffer pitch alignmentLaurent Pinchart1-1/+18
The DU requires a 16 pixels pitch alignement. Make sure dumb buffers are allocated with the correct pitch, and validate the pitch when creating frame buffers. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2013-07-05drm/rcar-du: Don't ignore rcar_du_crtc_create() return valueLaurent Pinchart1-2/+5
Handle error cases correctly. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2013-06-27drm: Renesas R-Car Display Unit DRM driverLaurent Pinchart1-0/+245
The R-Car Display Unit (DU) DRM driver supports both superposition processors and all eight planes in RGB and YUV formats with alpha blending. Only VGA and LVDS encoders and connectors are currently supported. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
