Till the OMAP clocks are correctly defined in device tree, use this temporary hack to provide clock alias to the USB PHY clocks. Without this, USB Host & Ethernet will not be functional with device tree boots on Panda and uEVM. Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
