Otherwise we cannot limit new mux code to mach-omap2. The same signal names should eventually work for other omaps under mach-omap2. Note that these pins don't need to be OMAP_PIN_INPUT_PULLUP, just OMAP_PIN_INPUT is enough. Cc: Jarkko Nikula <jhnikula@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
