The XHCI controller is required to enter D3hot rather than D3cold for AMD s2idle on this hardware generation.
Otherwise, the 'Controller Not Ready' (CNR) bit is not being cleared by host in resume and eventually this results in xhci resume failures during the s2idle wakeup.

Any reason you resent us a patch that is already in a stable release?
And why not just use the stable kernel trees as-is? Why attempt to cherry-pick random portions of them?
thanks,
