StarFive JH7100 and JH7110 RISC-V SoC pin controllers
Pin multiplexing and GPIO controllers built into StarFive's JH7100 and JH7110 RISC-V application processors, which power single-board computers like the VisionFive and VisionFive 2 as well as the FET7110-C industrial core board. Without these, the SoC's pins can't be routed to UARTs, I2C, SPI, SD, and other on-chip peripherals.
recommendation
It should stay because the hardware is still in mass production and on sale in 2025 (VisionFive 2 SBC and FET7110-C industrial module), and the code is actively maintained upstream — including a June 2025 patch broadening compile-test coverage and an April 2025 series adding new pinctrl features for the JH7110. Deployments are modest today, but as one of the more popular RISC-V development platforms it is a strategic piece of Linux's RISC-V story.

codex reasoning notes (technical)
Real SoC-specific pinctrl/GPIO drivers for StarFive JH7100 and JH7110, with no natural generic replacement. Local repo evidence from `rg` and `git -c safe.directory=... log -- drivers/pinctrl/starfive` showed active, non-removal maintenance through 2026-01-18 (API updates, bug fixes, compile-test enablement). URLs were obtained via web search: openwall result for a 2025 compile-test patch, lore-kernel mirror result for a 2025 JH7110 feature series, LKDDb for ongoing kernel presence, and StarFive/RVSpace product-doc pages for current JH7110 hardware availability. Overall this looks like a niche but live RISC-V/industrial platform, so keep rather than deprecate.
