Subject: [PATCH 02/11] ARM: tegra: Remove VBUS_GPIO handling from board files
Date: Fri, 30 Mar 2012 16:59:55 -0600	[thread overview]
Message-ID: <1333148404-17691-3-git-send-email-swarren@wwwdotorg.org> (raw)
In-Reply-To: <1333148404-17691-1-git-send-email-swarren@wwwdotorg.org>

From: Stephen Warren <swarren@nvidia.com>

Instead of having board files manually request and initialize USB VBUS
GPIOs, fill in the USB driver's platform data and have it do it.
