The driver defines five GPIO communities with pad groups GPP_A through GPP_K, vGPIO and JTAG, and matches ACPI hardware ID INT34C6. The kernel module build infrastructure and the wiring into files.x86 are included. Reviewed by: vexeduxr MFC after: 1 week Sponsored by: Beckhoff Automation GmbH & Co.
