Subject: Re: [PATCH v6 0/4] add syscon driver based on regmap for general
 registers access

Hi Samuel,

The series needs to go via mfd or arm-soc tree as a whole.  In case
you want to take it through mfd tree, here is my ack.

Acked-by: Shawn Guo <shawn.guo@...aro.org>

Otherwise, I can take it via arm-soc tree with your ack.

Regards,
Shawn
