+ Say yes here to support GPIO interface on Intel Poulsbo SCH.
+ The Intel SCH contains a total of 14 GPIO pins. Ten GPIOs are
+ powered by the core power rail and are turned off during sleep
+ modes (S3 and higher). The remaining four GPIOs are powered by
+ the Intel SCH suspend power supply. These GPIOs remain
+ active during S3. The suspend powered GPIOs can be used to wake the
+ system from the Suspend-to-RAM state.
+
+ This driver can also be built as a module. If so, the module
+ will be called sch-gpio.
