drm: rcar-du: lvds: Fix LVDS startup on R-Car Gen2

2018-05-30T06:17:44Z

[ Upstream commit 8525d04ba8a6a9ecfa4bd619c988ca873a5fc2a4 ] According to the latest revision 2.00 of the R-Car Gen2 manual, the LVDS and the bias circuit must be enabled after the LVDS I/O pins are enabled, not before. Fix the Gen2 LVDS startup sequence accordingly. While at it, also fix the comment preceding the first LVDCR0 write that still talks about hardcoding the LVDS mode 0.

drm: rcar-du: Clip planes to screen boundaries

2017-12-04T16:38:31Z

Unlike the KMS API, the hardware doesn't support planes exceeding the screen boundaries or planes being located fully off-screen. We need to clip plane coordinates to support the use case. Fortunately the DRM core offers a drm_atomic_helper_check_plane_state() helper that validates the scaling factor and clips the plane coordinates. Use it to implement the plane atomic check and use the clipped source and destination rectangles from the plane state instead of the unclipped source and CRTC coordinates to configure the device.

drm: rcar-du: Share plane atomic check code between Gen2 and Gen3

2017-12-04T11:04:11Z

The plane atomic check implementation is identical on Gen2 (DU planes) and Gen3 (VSP planes), but two separate functions exist as they operate on different data structures. Refactor the code to share the implementation. Signed-off-by: Laurent Pinchart Tested-by: Kieran Bingham Reviewed-by: Kieran Bingham

drm: rcar-du: Remove unused CRTC suspend/resume functions

2017-12-04T11:04:11Z

An early implementation of suspend-resume helpers are available in the CRTC module, however they are unused and no longer needed. With suspend and resume handled by the core DRM atomic helpers, we can remove the unused functions. Signed-off-by: Kieran Bingham Reviewed-by: Laurent Pinchart

drm: rcar-du: Implement system suspend/resume support

2017-12-04T11:04:11Z

To support system suspend operations we must ensure the hardware is stopped, and resumed explicitly from the suspend and resume handlers. Implement suspend and resume functions using the DRM atomic helper functions. Signed-off-by: Kieran Bingham Reviewed-by: Laurent Pinchart

drm: rcar-du: Don't set connector DPMS property

2017-12-04T11:04:11Z

Since commit 4a97a3da420b ("drm: Don't update property values for atomic drivers") atomic drivers must not update property values as properties are read from the state instead. To catch remaining users, the drm_object_property_set_value() function now throws a warning when called by atomic drivers on non-immutable properties, and we hit that warning when creating connectors. The easy fix is to just remove the drm_object_property_set_value() as it is used here to set the initial value of the connector's DPMS property to OFF. The DPMS property applies on top of the connector's state crtc pointer (initialized to NULL) that is the main connector on/off control, and should thus default to ON.
