Subject: [PATCH v3 12/19] usb: dwc3: add rx_detect to polling lfps quirk
Date: Tue, 28 Oct 2014 19:54:33 +0800 [thread overview]
Message-ID: <1414497280-3126-13-git-send-email-ray.huang@amd.com> (raw)
In-Reply-To: <1414497280-3126-1-git-send-email-ray.huang@amd.com>
This patch adds RX_DETECT to Polling.LFPS control quirk, and some special
platforms can configure that if it is needed.
Signed-off-by: Huang Rui <ray.huang@amd.com>
