The current PHY2 LED define are wrong and actually set BITs outside the related mask. Fix it and set the correct value. While at it, also use FIELD_PREP_CONST macro to make it simple to understand what values are actually applied for the mask. Also fix wrong PHY LED mapping. The SoC Switch supports up to 4 port but the register define mapping for 5 PHY port, starting from 0. The mapping was wrongly defined starting from PHY1. Reorder the function group to start from PHY0. PHY4 is actually never supported as we don't have a GPIO pin to assign.

2025-04-15pinctrl: mcp23s08: Reset all pins to input at probeMike Looijmans1-0/+8
At startup, the driver just assumes that all registers have their default values. But after a soft reset, the chip will just be in the state it was, and some pins may have been configured as outputs. Any modification of the output register will cause these pins to be driven low, which leads to unexpected/unwanted effects. To prevent this from happening, set the chip's IO configuration register to a known safe mode (all inputs) before toggling any other bits.

In atmel_pctl_dt_subnode_to_map(), the return value of pinctrl_utils_add_map_mux() needs to be checked, for the function will fail to associate group when the group map is full. Add error handling for pinctrl_utils_add_map_mux() to return immediately and propagate the error code to caller function when the function fails.

2025-04-09pinctrl: amd: Add an LPS0 check() callbackMario Limonciello1-0/+34
During suspend the pinctrl_amd driver disables the interrupts for any GPIOs that are not marked as wake sources. This however does not prevent them from changing the wake status bit during suspend, it just stops the system from waking. If the system wakes from hardware sleep for another reason (such as plugging in the AC adapter) this wake bits might be active. This could potentially cause problems with going back to hardware sleep. Add an extra debugging message when PM debugging is enabled to help identify if this is happening.

2025-04-08pinctrl: samsung: Add filter selection support for alive bank on gs101Peter Griffin2-0/+54
Newer Exynos based SoCs have a filter selection bitfield in the filter configuration registers on alive bank pins. This allows the selection of a digital or analog delay filter for each pin. Add support for selecting and enabling the filter. On suspend we set the analog filter to all pins in the bank (as the digital filter relies on a clock). On resume the digital filter is reapplied to all pins in the bank. The digital filter is working via a clock and has an adjustable filter delay flt_width bitfield, whereas the analog filter uses a fixed delay. The filter determines to what extent signal fluctuations received through the pad are considered glitches. The code path can be exercised using echo mem > /sys/power/state And then wake the device using a eint gpio Reviewed-by: André Draszik <andre.draszik@linaro.org> Signed-off-by: Peter Griffin <peter.griffin@linaro.org> Link: https://lore.kernel.org/r/20250402-pinctrl-fltcon-suspend-v6-4-78ce0d4eb30c@linaro.org Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

2025-04-08pinctrl: samsung: add dedicated SoC eint suspend/resume callbacksPeter Griffin3-85/+97
Refactor the existing platform specific suspend/resume callback so that each SoC variant has it's own callback containing the SoC specific logic. This allows exynosautov920 to have a dedicated function for using eint_con_offset and eint_mask_offset. Also it is easily extendable for gs101 which will need dedicated logic for handling the varying register offset of fltcon0 via eint_fltcon_offset.
