usb: add devicetree helpers for determining dr_mode and phy_type
This adds two little devicetree helper functions for determining the dr_mode (host, peripheral, otg) and phy_type (utmi, ulpi,...) from the devicetree. [Backport from uncommitted patch to 3.10 - Added the dr_mode to the bindings txt file ] Change-Id: Id535eff4da66726cf74e5cba0f39a5a93432999c Signed-off-by: Michael Grzeschik <m.grzeschik@pengutronix.de> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Acked-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Alexander Shishkin <alexander.shishkin@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Ruchika Kharwar <ruchika@ti.com>
