There was discussion (for all SoCs) about the presence of the arm,data-latency and arm,tag-latency properties. Given the mess^H^H^H^H presence or absence of virtualization they may or may not be valid... I think the way forward (keeping the dependency for SYSC PM Domains in mind) is to apply the series, after removing the controversial latency properties. Should I resend, or can/will you handle that?
