Subject: [PATCH v4 07/16] usb: dwc3: add dis_enblslpm_quirk
Date: Mon, 11 May 2020 15:55:11 +0800	[thread overview]
Message-ID: <20200511075520.26557-3-frank.wang@rock-chips.com> (raw)
In-Reply-To: <20200511075520.26557-1-frank.wang-TNX95d0MmH7DzftRWevZcw@public.gmane.org>

Add a quirk to clear the GUSB2PHYCFG.ENBLSLPM bit, which controls
whether the PHY receives the suspend signal from the controller.

Refer to commit ec791d149bca("usb: dwc3: Add dis_enblslpm_quirk")
in Linux Kernel.
