When operating in DU output mode (deep pipeline to the DU through the LIF), the VSP1 needs to constantly supply frames to the display. To ensure reuse the last queued buffer instead of returning it to the user. Signed-off-by:

When a fatal error that prevents any further video streaming occurs in a pipeline, all queued buffers must be marked as erroneous and new buffers must be prevented from being queued. Implement this behaviour with a new omap4iss_pipeline_cancel_stream() function that can be used by submodules to cancel streaming. Signed-off-by:

Instead of manually checking whether the CSI2 module is CSI2a or CSI2b in order to select the right subclock to enable/disable, add a subclk field to the iss_csi2 structure, initialize it with the corresponding subclock value and use it at runtime. Signed-off-by:

When a failure to stop a module in the pipeline is detected, the only way to recover is to reset the ISS. However, as other users can be using a different pipeline with other modules, the ISS can't be reset synchronously with the error detection. Keep track of modules that have failed to stop, and reset the ISS accordingly when the last user releases the last reference to the ISS. Refuse to start streaming on a pipeline that contains a crashed module, as the hardware wouldn't work anyway. Modify the omap4iss_pipeline_set_stream() function to record the new ISS pipeline state only when no error occurs, except when stopping the pipeline in which case the pipeline is still marked as stopped.

ISP interrupts are enabled/disabled when starting/stopping the IPIPEIF or resizer. This doesn't permit using the two modules in separate pipelines. Fix it by enabling/disabling the ISP interrupts at the same time as the ISS interrupts, in the ISS device get/put operations. Signed-off-by:

Return an error from the s_stream handlers when stopping the stream failed instead of just logging the error and ignoring it. While we're at it, move the logging code from submodules to the driver code. Signed-off-by:

When stopping the resizer due to a buffer underrun, disabling RZA only produces input FIFO overflows, most probably when the next frame is received. Disable the whole resizer to work around the problem. Signed-off-by:

The ISIF generates VD0 interrupts even when writes are disabled. Disabling the ISIF when no buffer is available is thus not be enough, we need to handle the situation explicitly. Signed-off-by:

When VPDMA fetches or writes to an image buffer, the line stride must be a multiple of 16 bytes. If it isn't, VPDMA HW will write/fetch until the next 16 byte boundry. This causes VPE to work incorrectly for source or destination widths which don't satisfy the above alignment requirement. In order to prevent this, we now make sure that when we set pix format for the input and output buffers, the VPE source and destination image line strides are 16 byte aligned. Also, the motion vector buffers for the de-interlacer are allocated in such a way that it ensures the same alignment. Signed-off-by:

The data_type value to be programmed in the data descriptors to fetch/write a UYVY buffer was not mentioned correctly in the older DRA7x documentation. This caused VPE to fail with UYVY color formats. Update the data_type value to fix functionality when UYVY format is used. Signed-off-by:
