Clang warns (or errors with CONFIG_WERROR=y / W=e): pinctrl/mediatek/pinctrl-airoha.c:2064:41: error: variable 'an7583_pinctrl_drive_e2_conf' is not needed and will not be emitted [-Werror,-Wunneeded-internal-declaration] 2064 | static const struct airoha_pinctrl_conf an7583_pinctrl_drive_e2_conf[] = { | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ Due to a typo, an7583_pinctrl_drive_e2_conf is only used within ARRAY_SIZE() (hence no instance of -Wunused-variable), which is evaluated at compile time, so it will not be needed in the final object file.

2025-10-29pinctrl: stm32: fix hwspinlock resource leak in probe functionHaotian Zhang
In stm32_pctl_probe(), hwspin_lock_request_specific() is called to request a hwspinlock, but the acquired lock is not freed on multiple error paths after this call. This causes resource leakage when the function fails to initialize properly. Use devm_hwspin_lock_request_specific() instead of hwspin_lock_request_specific() to automatically manage the hwspinlock resource lifecycle.

2025-10-29pinctrl: mcp23s08: init reg_defaults from HW at probe and switch cache typeMaksim Kiselev
The probe function does not guarantee that chip registers are in their default state. Thus using reg_defaults for regmap is incorrect. For example, the chip may have already been configured by the bootloader before the Linux driver loads, or the mcp might not have a reset at all and not reset a state between reboots. In such cases, using reg_defaults leads to the cache values diverging from the actual registers values in the chip. Previous attempts to fix consequences of this issue were made in 'commit 3ede3f8b4b4b ("pinctrl: mcp23s08: Reset all pins to input at probe")', but this is insufficient. The OLAT register reset is also required. And there's still potential for new issues arising due to cache desynchronization of other registers. Therefore, remove reg_defaults and provide num_reg_defaults_raw. In that case the cache defaults being initialized from hardware. Also switch cache type to REGCACHE_MAPLE, which is aware of (in)valid cache entries. And remove the force reset all pins to input at probe as it is no longer required.

Devices in the stm32mp2xx family include an I/O synchronization block on each pin that is used to fine tune and improve the I/O timing margins of high speed synchronous interfaces. It can be configured to provide independently for each pin: - skew rate on input direction or latch delay on output direction; - inversion of clock signals or re-sampling of data signals. Add support for the generic properties: - skew-delay-input-ps; - skew-delay-output-ps. Add support for the property 'st,io-sync' to configure clock inversion or data re-sampling mode.
