The patch was sent on Feb 4, I would expect that to be close enough. Does this
need to be the month of the kernel release it is merged into instead?

The original patch was specific to a particular SoC vendor. Since the
information provided here is fairly generic in the end, I asked for
the interface
to be generalized to the point that it can be reused across multiple
