Intel SoC and PCH Pin Controllers

Pin multiplexing and GPIO controllers built into Intel's x86 SoCs and platform controller hubs, responsible for routing the hundreds of chip pins between functions like I2C, SPI, UART, and general-purpose I/O. The hardware spans a decade of Intel platforms, from older Core and Atom parts up through Alder Lake, Raptor Lake, Lunar Lake, and Arrow Lake systems sold in 2025.

recommendation

It should stay in the kernel because it provides the pin multiplexing and GPIO control for virtually every modern Intel client and server platform, including Alder Lake, Raptor Lake, Lunar Lake, Panther Lake, and Arrow Lake. Upstream maintenance is clearly active, with patches landing as recently as 2024 and 2026 and new platform support being added on an ongoing basis. There is no alternative driver because this is the canonical Intel-authored support for these chips.

codex reasoning notes (technical)

Keep: this is an active Intel pinctrl/GPIO driver family with recent lore activity and new-platform enablement, not an orphaned legacy block. No natural replacement exists because it is the platform-specific upstream driver for these Intel SoC/PCH pin controllers. URLs were obtained via lore_activity MCP (first two lore links) and web search (LKDDb and Intel datasheet pages).
