Subject: [PATCH] usb: host: xhci-plat: suspend/resume clks for brcm
Git-commit: c69400b09e471a3f1167adead55a808f0da6534a
Patch-mainline: v6.1-rc1
References: git-fixes
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.
