Shawn,

IIUC, you are the de facto maintainer of arch/arm64/boot/dts/freescale
entry, thus adding you to the loop.
I'd like to get the Ack for this patch.

As stated in the cover letter: https://lkml.org/lkml/2016/5/5/340
my intent is to go with the whole patch set via cryptodev-2.6 tree.

Thanks,
Horia
