From 864cf949981754c53de0a2efdc6c542c51d61328 Mon Sep 17 00:00:00 2001 From: Peter Chen Date: Tue, 24 Sep 2013 12:47:55 +0800 Subject: usb: chipidea: add ci_hdrc_enter_lpm API This API is used to let the PHY enter/leave low power mode. Before the controller going to work(at probe/resume), it needs to let the PHY leave low power mode. After the controller stopping working(at remove/suspend), it needs to let the PHY enter low power mode to save power consumption.
