pinctrl: stm32: Drop the nonexistent CONFIG_MACH_STM32MP25 from the STM32MP257 default

2026-09-16T16:41:27+00:00

Commit 619f8ca4a73d ("pinctrl: stm32: add stm32mp257 pinctrl support") made CONFIG_PINCTRL_STM32MP257 default to MACH_STM32MP25, following the MACH_* pattern of the arm32 entries above it, but no Kconfig symbol of that name exists and git log -S finds no Kconfig file that ever defined one: the STM32MP25 family is arm64 only, where CONFIG_ARCH_STM32 covers it. Commit dba0aff2b89b ("pinctrl: stm32: Allow compile as module for stm32mp257") added "|| (ARCH_STM32 && ARM64)" next to it, so the first half now evaluates to n and changes no configuration. Drop the first half. Fixes: 619f8ca4a73d ("pinctrl: stm32: add stm32mp257 pinctrl support") Assisted-by: LLM Signed-off-by: Karl Mehltretter Reviewed-by: Antonio Borneo Signed-off-by: Linus Walleij

pinctrl: stm32: fix HDP driver dependency on GPIO_GENERIC

2026-03-19T15:44:45+00:00

The HDP driver uses the generic GPIO chip API, but this configuration may not be enabled. Ensure it is enabled by selecting the appropriate option. Fixes: 4bcff9c05b9d ("pinctrl: stm32: use new generic GPIO chip API") Signed-off-by: Amelie Delaunay Signed-off-by: Linus Walleij

pinctrl: stm32: Introduce HDP driver

2025-07-14T15:50:58+00:00

This patch introduce the driver for the Hardware Debug Port available on STM32MP platforms. The HDP allows the observation of internal SoC signals by using multiplexers. Each HDP port can provide up to 16 internal signals (one of them can be software controlled as a GPO).
