It's powertip,ph800480t013-idf02

Could you please point to any documentation for this?

Git log would point you to it: 

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=051e95ee7ec10050154e4c8f48be4d99ac83f8fc

Timing patterns we use differ from powertip,ph800480t013-idf02.

https://github.com/beagleboard/linux/commit/bde1b4c52cc5a79a2108076b8706e23d5844afa9

So I think, separate compatible needs to be added.
