Are there kernels for N7 Grouper with Tap2Wake and 5.1.x support?

Hello all,...
I am running an unlocked N7 2012 Grouper with TWRP2.8.7.0, Lollipop 5.1.1 Rom from Chroma and right now the M-Kernel 5.1.
I really would like to have the Tap to Wake or Double Tap to Wake feature but can't find a Kernel which supports that.
Earlier versions of the M-Kernel should, but the actual version isn't, so I am wondering if there are other kernels which support that feature.
I love it on my HTC and also on my Z3 compact, and it would be so great if that feature could also make it to my N7 ;)

Any help or hint is really welcome..

Many thanks in advance...
