After having switched to dynamic trip points, we no longer have a
hardware limit for trip point count and can support as many as we want
without polling.

This will need to wait for release after driver changes get accepted.
You sent your patchset just after merge window started, so unfortunately
this means it will get in 2 releases.

Best regards,
