Date: Thu, 16 Apr 2015 18:03:04 +1000 Message-ID: <20150416080304.23307.55760.stgit@notabene.brown> References: <20150416075945.23307.24424.stgit@notabene.brown> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <20150416075945.23307.24424.stgit@notabene.brown> Sender: linux-kernel-owner@vger.kernel.org To: Kishon Vijay Abraham I Cc: Tony Lindgren , GTA04 owners , linux-omap@vger.kernel.org, linux-kernel@vger.kernel.org, Pavel Machek List-Id: linux-omap@vger.kernel.org The USB phy should initialize with power-off, and will be powered on by the USB system when a cable connection is detected. Having this pm_runtime_get_sync() during probe causes the phy to *always* be powered on. Removing it returns to sensible power management.
