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 <laurent.pinchart+renesas@ideasonboard.com>

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 authored
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: -

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.

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:

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. Signed-off-by:

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:

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.

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:

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:

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:

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. Signed-off-by:

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:

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:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

The rwpf field contains a pointer to the rpf or wpf associated with the video node. Instead of storing it as a vsp1_entity, store the corresponding vsp1_rwpf pointer to allow accessing the vsp1_rwpf fields directly. Signed-off-by:
