2016-02-23drm: rcar-du: Drop LVDS double dependency on OFLaurent Pinchart1-1/+0
LVDS support depends on DRM_RCAR_DU which already depends on OF. Drop the explicit dependency. Signed-off-by: Laurent Pinchart <[email protected]>
2016-02-23drm: rcar-du: Enable compilation on ARM64Koji Matsuoka1-1/+2
The R8A7795 SoC is ARM64-based and include a DU. Enable driver compilation on ARM64. Signed-off-by: Koji Matsuoka <[email protected]> Signed-off-by: Laurent Pinchart <[email protected]>
2016-02-23drm: rcar-du: Fix compile warning on 64-bit platformsKoji Matsuoka1-4/+4
Use %tu instead of %u to print difference between pointers. Signed-off-by: Koji Matsuoka <[email protected]> Signed-off-by: Laurent Pinchart <[email protected]>
2016-02-23drm: rcar-du: Expose the VSP1 compositor through KMS planesLaurent Pinchart10-16/+539
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 <[email protected]>
2016-02-20drm: rcar-du: Move plane allocator to rcar_du_plane.cLaurent Pinchart3-275/+290
The plane allocator is specific to DU planes and won't be used for VSP-based planes, move it with the rest of the DU planes code where it belongs. Signed-off-by: Laurent Pinchart <[email protected]>
2016-02-20drm: rcar-du: Restart the DU group when a plane source changesLaurent Pinchart4-2/+28
Plane sources are configured by the VSPS bit in the PnDDCR4 register. Although the datasheet states that the bit is updated during vertical blanking, it seems that updates only occur when the DU group is held in reset through the DSYSR.DRES bit. Restart the group if the source changes. Signed-off-by: Laurent Pinchart <[email protected]>
2016-02-20drm: rcar-du: Add VSP1 compositor supportLaurent Pinchart6-49/+82
Configure the plane source at plane setup time to source frames from memory or from the VSP1. Signed-off-by: Laurent Pinchart <[email protected]>
2016-02-20drm: rcar-du: Add VSP1 support to the planes allocatorLaurent Pinchart3-6/+44
The R8A7790 DU can source frames directly from the VSP1 devices VSPD0 and VSPD1. VSPD0 feeds DU0/1 plane 0, and VSPD1 feeds either DU2 plane 0 or DU0/1 plane 1. Allocate the correct fixed plane when sourcing frames from VSPD0 or VSPD1, and allocate planes in reverse index order otherwise to ensure maximum availability of planes 0 and 1. Signed-off-by: Laurent Pinchart <[email protected]>
2016-02-20drm: rcar-du: Refactor plane setupLaurent Pinchart1-18/+21
Rename plane setup functions using more explicit names, and use local variables to store intermediate values to increase readability. This also prepares for VSP compositor support. Signed-off-by: Laurent Pinchart <[email protected]>
2016-02-20drm: rcar-du: Compute plane DDCR4 register value directlyLaurent Pinchart1-10/+3
There's no need for a read-modify-write pattern, all register bits can be set explicitly. Signed-off-by: Laurent Pinchart <[email protected]>
2016-02-20drm: rcar-du: Don't update planes on disabled CRTCsLaurent Pinchart1-1/+1
A disabled CRTC can't display planes, the driver shouldn't try to configure it when updating planes. The DRM core will store the plane state for us, and the plane will be configured appropriately the next time the CRTC is enabled. Signed-off-by: Laurent Pinchart <[email protected]>
2016-02-20drm: rcar-du: Remove local CRTC enabled stateLaurent Pinchart2-13/+1
The atomic framework guarantees that the CRTC enable and disable functions will only be called when needed, there's no need to duplicate the CRTC state check. By replacing the local CRTC enabled state check at resume time with the CRTC active state we can remove the local CRTC enabled state altogether. Signed-off-by: Laurent Pinchart <[email protected]>
2016-02-20drm: rcar-du: Perform initialization/cleanup at probe/remove timeLaurent Pinchart4-114/+106
The drm driver .load() operation is prone to race conditions as it initializes the driver after registering the device nodes. Its usage is deprecated, inline it in the probe function and call drm_dev_alloc() and drm_dev_register() explicitly. For consistency inline the .unload() handler in the remove function as well.

2016-02-19[media] v4l: vsp1: Configure device based on IP versionLaurent Pinchart11-117/+116
The IP version number carries enough information to identify the exact device instance features. Drop the related DT properties and use the IP version instead. Signed-off-by: Laurent Pinchart <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2016-02-19[media] v4l: vsp1: Add display list supportTakashi Saito14-95/+543
Display lists contain lists of registers and associated values to be applied atomically by the hardware. They lower the pressure on interrupt processing delays when reprogramming the device as settings can be prepared well in advance and queued to the hardware without waiting for the end of the current frame. Display list support is currently limited to the DRM pipeline.

2016-02-19[media] v4l: vsp1: Add support for the R-Car Gen3 VSP2Laurent Pinchart4-16/+62
Add DT compatible strings for the VSP2 instances found in the R-Car Gen3 SoCs and support them in the vsp1 driver. Signed-off-by: Laurent Pinchart <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2016-02-19[media] v4l: vsp1: Implement atomic update for the DRM driverLaurent Pinchart3-20/+66
Add two API functions named vsp1_du_atomic_begin() and vsp1_du_atomic_flush() to signal the start and end of an atomic update. The vsp1_du_setup_rpf() function is renamed to vsp1_du_atomic_update() for consistency. With this new API, the driver will reprogram all modified inputs atomically before restarting the video stream.

2016-02-19[media] v4l: vsp1: Add VSP+DU supportLaurent Pinchart6-11/+625
Implement internal control of the VSP pipeline to be used by the DU DRM/KMS driver when using the VSP as an internal composer handled through DRM/KMS only. Signed-off-by: Laurent Pinchart <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2016-02-19[media] v4l: vsp1: Don't validate links when the userspace API is disabledLaurent Pinchart12-17/+27
As the pipeline is configured internally by the driver when the userspace API is disabled its configuration can be trusted and link validation isn't needed. Signed-off-by: Laurent Pinchart <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2016-02-19[media] v4l: vsp1: Set the alpha value manually in RPF and WPF s_stream handlersLaurent Pinchart3-5/+20
The RPF and WPF alpha values are set through V4L2 controls and applied when starting the video stream by a call to v4l2_ctrl_handler_setup(). As that function uses the control handler mutex it can't be called in interrupt context, where the VSP+DU pipeline handler might need to reconfigure the pipeline. Set the alpha value manually in the RPF and WPF s_stream handler to ensure that the hardware is properly configured even when controlled without the userspace API. If the userspace API is enabled protect that with the control lock to avoid race conditions with userspace. Signed-off-by: Laurent Pinchart <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2016-02-19[media] v4l: vsp1: Make pipeline inputs array index by RPF indexLaurent Pinchart4-7/+22
The pipeline inputs array stores pointers to all RPFs contained in the pipeline. It's currently indexed contiguously by adding RPFs in the order they are found during graph walk. This can't easily support dynamic addition and removal of RPFs while streaming, which will be required for combined VSP+DU support. Make the array indexed by RPF index instead and skip NULL elements when iterating over RPFs.

2016-02-19[media] v4l: vsp1: Make the userspace API optionalLaurent Pinchart5-23/+38
The R-Car Gen3 SoCs include VSP instances dedicated to the DU that will be controlled entirely by the rcar-du-drm driver through the KMS API. To support that use case make the userspace V4L2 API optional. Signed-off-by: Laurent Pinchart <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2016-02-19[media] v4l: vsp1: Move format info to vsp1_pipe.cLaurent Pinchart4-154/+159
Format information and the related helper function are not specific to the V4L2 API, move them from vsp1_video.c to vsp1_pipe.c. Signed-off-by: Laurent Pinchart <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2016-02-19[media] v4l: vsp1: Make the BRU optionalLaurent Pinchart2-6/+10
Not all VSP instances have a BRU on R-Car Gen3, make it optional. Set the feature unconditionally for now, this will be fixed when adding Gen3 support. Signed-off-by: Laurent Pinchart <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2016-02-19[media] v4l: vsp1: Make number of BRU inputs configurableLaurent Pinchart5-12/+18
The R-Car Gen3 family has 5-inputs BRUs, support them by making the number of BRU inputs configurable. As the driver assumes that the number of BRU inputs is equal to the number of RPFs, replace the BRU_MAX_INPUTS macro with VSP1_MAX_RPF to make the assumption apparent.

2016-02-19[media] v4l: vsp1: Decouple pipeline end of frame processing from vsp1_videoLaurent Pinchart2-8/+19
To make the pipeline structure and operations usable without video devices the frame end processing must be decoupled from struct vsp1_video. Implement this by calling the video frame end function indirectly through a function pointer in struct vsp1_pipeline.

2016-02-19[media] v4l: vsp1: Move vsp1_video pointer from vsp1_entity to vsp1_rwpfLaurent Pinchart4-11/+11
Only RPFs and WPFs can be associated with video nodes, don't waste memory by storing the video pointer in all entities. Signed-off-by: Laurent Pinchart <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2016-02-19[media] v4l: vsp1: Support VSP1 instances without any UDSLaurent Pinchart2-2/+3

2016-02-19[media] v4l: vsp1: Make rwpf operations independent of video deviceLaurent Pinchart5-27/+35
The rwpf queue operation doesn't queue a buffer but sets the memory address for the next run. Rename it to set_memory and pass it a new structure independent of the video buffer than only contains memory information.

2016-02-19[media] v4l: vsp1: Move video device out of struct vsp1_rwpfLaurent Pinchart9-60/+63
To make the video device nodes optional we need to decouple the [rw]pf instances from the video devices. Move video devices out of struct vsp1_rwpf and instantiate them dynamically in the core driver code.
