[PATCH v14 0/4] New debugfs API for capturing CRC of frames

[Tomeu Vizoso]

Hi,

here are the patches that remain to be merged in this series.

Since v13, I have added a patch that makes open() block until the first
CRC comes. This is because otherwise, userspace would need to guess how
much time this particular HW takes to become ready to generate frame
CRCs. This patch could be dropped if it's preferred that userspace waits
for the first frame CRC to come before assuming that the HW is ready.

The other patches are unchanged.

Thanks,

Tomeu
