As part of the GPIO conversion to platform_device/platform_driver, commit 2fae7fbed072705d91e09ed393b2e580b2d895fc (OMAP: GPIO: prepare for platform driver) removed hard-coded per-bank SYSCONFIG register values in favor of using omap_hwmod to manage the SYSCONFIG register. In the previous code, bank-level wakeups were enabled by default using the SYSCONFIG.ENAWAKEUP bit, but omap_hwmod does not enable wakeups by default. Thus the above commit effectively disabled GPIO bank wakeups. This patch enables GPIO bank level wakeups by default to preserve previous functionality. Longer term, per-bank wakeup functionality should be controlled by the driver and enabled only when there are wakeup-enabled GPIOs in the bank. Tested on 36xx/Zoom3 where serial console (QUART) uses GPIO IRQ.
