CONFIG_GPIO_SCH: Intel SCH/TunnelCreek/Centerton GPIO

General informations

The Linux kernel configuration item CONFIG_GPIO_SCH has multiple definitions:

Intel SCH GPIO found in drivers/gpio/Kconfig

The configuration item CONFIG_GPIO_SCH:

Help text

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.

Say yes here to support GPIO interface on Intel Poulsbo SCH or Intel Tunnel Creek processor. 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.
