2016-07-29drm: rcar: use generic code for managing zpos plane propertyBenjamin Gaignard1-1/+0
version 6: rebased patch on top rcar-du changes for zpos version 4: fix null pointer issue while setting zpos in plane reset function This patch replaces zpos property handling custom code in rcar DRM driver with calls to generic DRM code.

2016-02-23drm: rcar-du: Add R8A7795 device supportLaurent Pinchart1-1/+3
Document the R8A7795-specific DT bindings and support them in the driver. The HDMI and LVDS outputs are currently not supported. Signed-off-by: Koji Matsuoka <koji.matsuoka.xm@renesas.com> Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2016-02-23drm: rcar-du: Support up to 4 CRTCsKoji Matsuoka1-1/+1
The Gen3 R8A7795 DU has 4 CRTCs, support them all. Signed-off-by: Koji Matsuoka <koji.matsuoka.xm@renesas.com> Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2016-02-23drm: rcar-du: Expose the VSP1 compositor through KMS planesLaurent Pinchart1-0/+4
On R-Car Gen3 SoCs the DU lost its ability to access memory directly and needs to work in conjunction with the VSP to do so. This commit handles the VSP internally to hide it from the user. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2016-02-20drm: rcar-du: Add VSP1 compositor supportLaurent Pinchart1-0/+2
Configure the plane source at plane setup time to source frames from memory or from the VSP1. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2015-05-25drm: rcar-du: Move properties from rcar_du_planes to rcar_du_deviceLaurent Pinchart1-0/+6
The plane property objects are instantiated once per CRTC group, while they should be instantiated once globally for the device. Fix this and move them to the rcar_du_device structure. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2015-03-03drm: rcar-du: Implement asynchronous commit supportLaurent Pinchart1-0/+6
Implement a custom .atomic_commit() handler that supports asynchronous commits using a work queue. This can be used for userspace-driven asynchronous commits, as well as for an atomic page flip implementation. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2015-03-03drm: rcar-du: Define macros for the max number of groups, CRTCs and LVDSLaurent Pinchart1-3/+7
Let's avoid magic constants. Beside increasing code readability, it will also ensure that no location will be forgotten when raising the maximum number of groups, CRTCs or LVDS encoders Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2014-12-23drm: rcar-du: Refactor DEFR8 featureLaurent Pinchart1-1/+1
Rename the feature from RCAR_DU_FEATURE_DEFR8 to RCAR_DU_FEATURE_EXT_CTRL_REGS to cover all extended control registers in addition to the DEFR8 register. Usage of the feature is refactored to optimize runtime operation and prepare for external clock support. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2014-11-26drm: rcar-du: Remove platform data supportLaurent Pinchart1-2/+0

2014-09-15drm/rcar-du: Update copyright noticeLaurent Pinchart1-1/+1
The "Renesas Corporation" listed in the copyright notice doesn't exist. Replace it with "Renesas Electronics Corporation" and update the copyright years. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2013-12-02drm/rcar-du: Add LVDS_LANES quirkLaurent Pinchart1-0/+1
LVDS lanes 1 and 3 are switched in ES1 hardware (R8A7790). The problem has been fixed in newer revisions, add a quirk to make the workaround selectable. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2013-12-02drm/rcar-du: Split features and quirksLaurent Pinchart1-2/+11
128-byte pitch alignement is not a hardware feature, it's a hardware bug. Split it from the features field into a new quirks field. New quirks will be added to support the R8A7791 SoC. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2013-08-10drm/rcar-du: Add FBDEV emulation supportLaurent Pinchart1-0/+2
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/+4
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: Configure RGB output routing to DPAD0Laurent Pinchart1-0/+2
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>
2013-08-10drm/rcar-du: Rework output routing supportLaurent Pinchart1-0/+16
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 DEFR8 registerLaurent Pinchart1-0/+1
The R8A7790 DU has a new extended function control register. Support it. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2013-08-10drm/rcar-du: Add support for multiple groupsLaurent Pinchart1-2/+4
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 Pinchart1-0/+1
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: Introduce CRTCs groupsLaurent Pinchart1-7/+3
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: Create rcar_du_planes structureLaurent Pinchart1-10/+1

2013-08-10drm/rcar-du: Support per-CRTC clock and IRQLaurent Pinchart1-1/+2
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>
2013-08-10drm/rcar-du: Add platform module device tableLaurent Pinchart1-0/+15
The platform device id driver data field points to a device information structure that only contains a (currently empty) features field for now. Support for additional model-dependent features will be added later. Only the R8A7779 variant is currently supported. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
2013-06-27drm: Renesas R-Car Display Unit DRM driverLaurent Pinchart1-0/+66
