The earlier approach of enabling wakeup on the touchscreen GPIO pin during board level mux init is removed. Instead the wakeup flag in ads7846_platform_data is enabled. Based on the flag, the ads7846 driver will do an enable_irq_wake which will eventually call into the OMAP GPIO layer and will enable the wakeup capability on the GPIO pin.
