I'm happy to invest my time to implement such functionality.
I think it can be really useful for LEDs array like CR0014114 <https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v5.5&id=b9dd69155371ebd7055c182e30423edc9104239f>.

In few days I can publish my vision,
but before that could you please explain why it will took months?
Where it can be hard to implement?

User-space don't fast enough to provide correct timings.
