On my side, I give my acknowledgement to the whole patch series:

Acked-by: Nicolas Ferre <nicolas.ferre@atmel.com>

I hope that once Fabio Porcedda's series is merged, this series can be
applied on top of it seamlessly and quickly.

Wim,
Tell us if you need that we resend this series or rebase it on top of
another git tree.

Thanks for your work and for your reviews.

Best regards,
