OMAP3: PM: Enable wakeup from ads7846 touchscreen
This patch enables the wakeup capabilities of ads7846 touchscreen driver. ads7846 driver can now wakeup the system from suspend on OMAP3430 EVM and SDP boards. 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.
