To avoid potentially overflowing the kernel logs in the case of corrupted streams, this commit replaces an error message with a per-stream counter to be read through a driver-specific control. Applications can read the per-stream accumulated error macroblocks count. The old error message is replaced by a rate-limited debug message. Signed-off-by:

It's possible that the VPU was initialized using just one buffer, containing only codec headers. In this case, right after the initialization and after updating the FIFO read pointer, we need to iterate through all the coda_buffer_meta and release any metas that have been already used by the VPU. This issue is affecting indirectly the bitstream buffer fill threshold, which depends on the meta end position of the first queued meta, which is passed to coda_bitstream_can_fetch_past(). Without this fix, it's possible that for certain videos, the bitstream buffer level is not filled properly, resulting in a PIC_RUN timeout. Reported-by:

MEDIA_BUS_FMT_METADATA_FIXED should be used when the same driver handles both sides of the link and the bus format is a fixed metadata format that is not configurable from userspace. The width and height will be set to 0 for this format. Signed-off-by:

isif_probe() invokes iounmap() on error handling paths, but it does not reset the global state. So, later it can invoke iounmap() even when ioremap() fails. This is the case also for isif_remove(). The patch resets the global state after invoking iounmap() to avoid this. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by:

For backward compatibility with older DTS where the bus-type property was not mandatory, assume V4L2_MBUS_PARALLEL as it was the only supported bus at the time. v4l2_fwnode_endpoint_alloc_parse() will not fail if 'bus-type' is not specified.

Earlier it was expected that there would be more variable size endpoint properties and that most if not all drivers would need them. For that reason it was expected also that v4l2_fwnode_endpoint_parse would no longer be needed. What actually happened that not all drivers require "link-frequencies", the only variable size media endpoint property without a small upper limit. Therefore drivers that do not need that information are fine using v4l2_fwnode_endpoint_parse. So don't tell drivers to use v4l2_fwnode_endpoint_alloc_parse in all cases. Signed-off-by:
