[PATCH i-g-t v7 0/1] usb: xhci: plat: Enable runtime PM

[Robert Foss]

This series enables runtime PM and asynchronous resume/suspend support for
xhci-plat devices.

Due to Baolin Wangs series[1] part 1/2 of this series is now dropped.

[PATCH i-g-t v7 1/1] usb: xhci: plat: Enable async suspend/resume

[Robert Foss]

From: Andrew Bresticker <abrestic@chromium.org>

USB host controllers can take a significant amount of time to suspend
and resume, adding several hundred miliseconds to the kernel resume
time. Since the XHCI controller has no outside dependencies (other than
clocks, which are suspended late/resumed early), allow it to suspend and
resume asynchronously.
