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. + The Intel Tunnel Creek processor has 5 GPIOs powered by the + core power rail and 9 from suspend power supply. This driver can also be built as a module. If so, the module will be called sch-gpio. |
