In-Reply-To: <1286288122-16834-1-git-send-email-eballetbo@gmail.com> References: <1286288122-16834-1-git-send-email-eballetbo@gmail.com> Message-ID: <1286288122-16834-2-git-send-email-eballetbo@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org GPIO for various devices are missing from the board initialization. This patch adds support for the VBUS and over current gpios. Without this patch, input/outputs from these two sources are ignored.
