From mboxrd@z Thu Jan 1 00:00:00 1970 From: Manu Gautam Subject: [PATCH v1 6/6] usb: dwc3: core: Notify USB3 PHY as well for DRD modes Date: Fri, 21 Jul 2017 16:32:01 +0530 Message-ID: <1500634921-25914-7-git-send-email-mgautam@codeaurora.org> References: <1500634921-25914-1-git-send-email-mgautam@codeaurora.org> Return-path: In-Reply-To: <1500634921-25914-1-git-send-email-mgautam@codeaurora.org> Sender: linux-kernel-owner@vger.kernel.org To: Kishon Vijay Abraham I , Felipe Balbi Cc: linux-arm-msm@vger.kernel.org, Manu Gautam , Greg Kroah-Hartman , "open list:DESIGNWARE USB3 DRD IP DRIVER" , open list List-Id: linux-arm-msm@vger.kernel.org Driver currently notifies only USB3 PHY for mode change. Extend this to USB3 PHY so that driver based on the mode can release system resources - clocks, regulators etc. and can even turn off PHY during runtime suspend.
