commit 8c7a3ccf54f93330830ef9ffd20e71d5834936ed Author: YannickV <[email protected]> AuthorDate: 2026-04-29 13:02:08 +0000 Commit: Corvin Köhne <[email protected]> CommitDate: 2026-08-06 06:41:54 +0000 gpio: add Intel Alder Lake-N GPIO driver Add a GPIO driver for the Intel Alder Lake-N platform based on the generic intelgpio framework. The driver provides pad group definitions for four GPIO communities covering groups GPP_A through GPP_T, vGPIO and HVCMOS, and matches ACPI hardware IDs INTC1056, INTC1057 and INTC1085. 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.
