[PATCH 6.0 798/862] usb: host: xhci-plat: suspend/resume clks for brcm

From: Greg Kroah-Hartman
Date: Wed Oct 19 2022 - 06:25:27 EST


From: Justin Chen <justinpopo6@xxxxxxxxx>

[ Upstream commit c69400b09e471a3f1167adead55a808f0da6534a ]

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.
