pinctrl: ultrarisc: Add UltraRISC DP1000 pinctrl driver

2026-06-11T13:02:35+00:00

Add support for the pin controller on the UltraRISC DP1000 SoC. The controller provides mux selection for pins in ports A, B, C, D, and LPC. Ports A-D default to GPIO and support peripheral muxing. LPC pins can be switched to eSPI, but are not available as GPIOs. Basic pin configuration controls such as drive strength, pull-up, and pull-down are also supported.

pinctrl: Move Airoha driver to dedicated directory

2026-06-08T08:15:16+00:00

In preparation for additional SoC support, move the Airoha pinctrl driver for AN7581 SoC to a dedicated directory. This is to tidy things up and keep code organized without polluting the Mediatek driver directory. The driver doesn't depend on any generic or common code from the Mediatek codebase so it can be safely moved without any modification.

pinctrl: add generic board-level pinctrl driver using mux framework

2026-05-05T12:48:55+00:00

Many boards use on-board mux chips (often controlled by GPIOs from an I2C expander) to switch shared signals between peripherals. Add a generic pinctrl driver built on top of the mux framework to centralize mux handling and avoid probe ordering issues. Keep board-level routing out of individual drivers and supports boot-time only mux selection. Ensure correct probe ordering, especially when the GPIO expander is probed later.

pinctrl: vt8500: Enable compile testing

2026-04-28T09:09:41+00:00

Enable compile testing for Realtek pin controller drivers for increased build and static checkers coverage. PINCTRL_WMT uses gpiochip_get_data(), thus needs GPIOLIB. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Linus Walleij

pinctrl: aspeed: Enable compile testing outside of ARCH_ASPEED

2026-04-28T09:09:41+00:00

Since inception in commit 4d3d0e4272d8 ("pinctrl: Add core support for Aspeed SoCs"), the Aspeed pin controller drivers cannot be compile tested, unless ARCH_ASPEED is selected. . That partially defeats the purpose of compile testing, since ARCH_ASPEED is pulled when building platform kernels. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Linus Walleij

pinctrl: realtek: Enable compile testing

2026-04-28T09:09:41+00:00

Enable compile testing for Realtek pin controller drivers for increased build and static checkers coverage. PINCTRL_RTD uses pinconf_generic_dt_node_to_map(), thus needs OF. Signed-off-by: Krzysztof Kozlowski Reviewed-by: Yu-Chun Lin Signed-off-by: Linus Walleij

pinctrl: tegra: Enable easier compile testing

2026-04-28T09:08:48+00:00

Currently NVIDIA Tegra pin controller drivers cannot be compile tested, unless ARCH_TEGRA is selected. That partially defeats the purpose of compile testing, since ARCH_TEGRA is pulled when building platform kernels. Solve it and allow compile testing independently of ARCH_TEGRA choice which requires few less usual changes: 1. Descent in Makefile in to drivers/pinctrl/tegra/ unconditionally, because there is no menu option. 2. Depend on COMMON_CLK for PINCTRL_TEGRA20, because it uses clk_register_mux().

pinctrl: add generic functions + pins mapper

2026-01-21T12:13:37+00:00

Add a generic function to allow creation of groups and functions at runtime based on devicetree content, before setting up mux mappings. It works similarly to pinconf_generic_dt_node_to_map(), and therefore parses pinconf properties and maps those too, allowing it to be used as the dt_node_to_map member of the pinctrl_ops struct.

pinctrl: move microchip riscv pinctrl drivers to a folder
