Andrey, thanks for the effort!

Herbert, Greg,

I hope it's ok to go with the fsl-mc bus dependency
"bus: fsl-mc: add api to retrieve mc version"
https://patchwork.kernel.org/patch/11447637/
included in this series through cryptodev-2.6 tree.

It applies cleanly on latest linux-next (next-20200320),
and it has been Acked-by Laurențiu (one of the fsl-mc bus maintainers).

Thank you,
Horia
