From mboxrd@z Thu Jan 1 00:00:00 1970 From: Roger Quadros Subject: [PATCH v2 2/2] ARM: dts: am57xx-beagle-x15: use palmas-usb for USB2 Date: Mon, 27 Jul 2015 16:10:17 +0300 Message-ID: <1438002617-15152-3-git-send-email-rogerq@ti.com> References: <1438002617-15152-1-git-send-email-rogerq@ti.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: In-Reply-To: <1438002617-15152-1-git-send-email-rogerq@ti.com> Sender: linux-kernel-owner@vger.kernel.org To: myungjoo.ham@samsung.com, cw00.choi@samsung.com, tony@atomide.com Cc: nm@ti.com, balbi@ti.com, linux-omap@vger.kernel.org, linux-kernel@vger.kernel.org, Roger Quadros List-Id: linux-omap@vger.kernel.org The VBUS line of USB2 is connected to VBUS detect logic on the PMIC. Use the palmas-usb driver to report VBUS events to the USB driver. As the palmas-usb driver supports GPIO based ID reporting provide the GPIO for ID pin as well.
