 An example of when you would want to use the pushbutton gpio is if you want to do something like determine if the user pushbutton has been held for a certain amount of time. This type of event is not available via the GSC interrupts because it involves starting a timer on a button-down event and counting the time expired before any button-up event occurs.
 
-The Linux kernel gpio-keys and gpio-keys-polled (and OpenWrt [wiki:OpenWrt/gpio#button-hotplug-gw gpio-button-hotplug]) drivers can be used to create Linux Input events from pushbuttons connected to GPIO's however if you want this functionality, you can use the gsc-input driver which is already enabled in the Gateworks BSP's. Note that the gpio-keys/gpio-keys-polled/gpio-button-hotplug drivers use the pushbutton gpio in a kernel driver therefore you can not export the gpio to userspace, where-as the gsc-input driver uses GSC interrupts for its information and therefore does not take control over the gpio.
