Subject: [PATCH 0/2] usb: host: xhci-plat: Introduce XHCI_SUSPEND_RESUME_CLKS quirk

From: Justin Chen <justinpopo6@...il.com>

Introduce XHCI_SUSPEND_RESUME_CLKS quirk for turning off clocks during suspend and
turning on clocks on resume. Certain hardware, in our case xhci_plat_brcm, can have
power savings by turning off clocks before hitting suspend states.

Justin Chen (2):
  usb: host: xhci-plat: suspend and resume clocks
  usb: host: xhci-plat: suspend/resume clks for brcm
