From 16199f33893922db8de8d3460384291b853051ec Mon Sep 17 00:00:00 2001 From: William Wu Date: Tue, 16 Aug 2016 22:44:37 +0800 Subject: usb: dwc3: add dis_u2_freeclk_exists_quirk Add a quirk to clear the GUSB2PHYCFG.U2_FREECLK_EXISTS bit, which specifies whether the USB2.0 PHY provides a free-running PHY clock, which is active when the clock control input is active.
