help
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.
