Yes this series had two another versions (v2,v3) posted by someone else.
However, I posted another v4 which is the latest one:
[RFC PATCH v4 0/5] ECAM quirks handling for ARM64 platforms
https://lkml.org/lkml/2016/6/28/165

In v4 there is one minor thing to be fixed. Do you want me to resend it
as v5 including mentioned fix ?

Thanks,
