From mboxrd@z Thu Jan 1 00:00:00 1970 From: Kishon Vijay Abraham I Subject: [PATCH v1 8/8] usb: otg: palmas-usb: fix cold plug issue Date: Fri, 25 Jan 2013 08:42:31 +0530 Message-ID: <1359083551-8524-9-git-send-email-kishon@ti.com> References: <1359083551-8524-1-git-send-email-kishon@ti.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: In-Reply-To: <1359083551-8524-1-git-send-email-kishon@ti.com> Sender: linux-kernel-owner@vger.kernel.org To: rob.herring@calxeda.com, rob@landley.net, balbi@ti.com, sameo@linux.intel.com, gg@slimlogic.co.uk, s-guiriec@ti.com, broonie@opensource.wolfsonmicro.com, linux-usb@vger.kernel.org, linux-omap@vger.kernel.org, linux-kernel@vger.kernel.org, linux-doc@vger.kernel.org, devicetree-discuss@lists.ozlabs.org Cc: grant.likely@secretlab.ca, gregkh@linuxfoundation.org, kishon@ti.com List-Id: devicetree@vger.kernel.org if the cable is connected even before the palmas-usb is loaded, the cable connect detection event will be missed. It's fixed here by checking for VBUS line states when palmas-usb is loaded.
