The ODDF signal, output by default on the ODDF pin, isn't used on any board supported in the kernel. As the Gen3 Salvator-X board uses the ODDF pin as a DISP signal, hardcode that configuration in the driver. Use of the ODDF signal will be implemented later through proper DT-based configuration of the DU pins. Signed-off-by: -

The DE signal is currently configured to be identical to the DISP signal and is used for the same purpose. To make it clearer that the DISP pin outputs the DISP signal, select it explicitly. Signed-off-by: -

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:

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 authored
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: -

Configure the plane source at plane setup time to source frames from memory or from the VSP1. Signed-off-by: -
Laurent Pinchart authored
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: -

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: -

There's no need for a read-modify-write pattern, all register bits can be set explicitly. Signed-off-by: -

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.

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 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.

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 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:
