Subject: usb: host: xhci-plat: suspend/resume clks for brcm
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c69400b09e471a3f1167adead55a808f0da6534a;p=linux.git

usb: host: xhci-plat: suspend/resume clks for brcm

The xhci_plat_brcm xhci block can enter suspend with clock disabled to save
power and re-enable them on resume. Make use of the XHCI_SUSPEND_RESUME_CLKS
quirk to do so.
