That's a patch for Samsung soc. I'll take it once binding is accepted.
If you send any new version of the patchset, please do not include DTS,
so the crypto maintainer could apply entire set easier.

Best regards,
Krzysztof

Thanks, Krzysztof! I'm going to send v3 soon, so I'll remove this
patch from the series.
