pinctrl: mediatek: use scnprintf() instead of snprintf()

2026-06-10T20:31:42Z

Replace snprintf() with scnprintf() in the MediaTek pinctrl driver. snprintf() returns the number of characters that _would_ have been written if the buffer were large enough, while scnprintf() returns the number of characters actually written to the buffer. Since we use the return value to advance the buffer pointer, we need to use scnprintf() to have the correct pointer arithmetic.

pinctrl: mediatek: mtk8189: set get_pinconf functions

2026-04-07T15:47:04Z

Set the get_pinconf functions for the mt8189 pinctrl driver. This will append pinconf bias info to the output of the pinmux status command. This is useful for debugging pin configuration issues.

pinctrl: mediatek: print bias info along with pinmux

2026-04-07T15:47:04Z

Add functionality to be able to print pin bias settings along with the pinmux setting. This can be useful to debug why pins might not be working correctly.

pinctrl: mediatek: mt8189: fix pinconf bias

2026-04-07T15:47:04Z

Fix setting pinconf bias for MT8189. Using mtk_pinconf_bias_set_v1() was wrong because MT8189 does not have PULLEN/PULLSEL registers. It has PU and PD registers for most pins. MSDC pins need special handling since they have PUPD/R1/R0 registers. I2C pins need special handling since they have PU/PD/RSEL registers. New groups are added for MSDC and I2C pins and the bias_set callback is now set appropriately for all groups. A new table is needed for the RSEL registers since those were missing. Some new macros are introduced to avoid repeating the same info many times in MTK_TYPED_PIN(). This also fixes the semantically incorrect use of DRV_GRPX for the IO_TYPE_GRPX field.

pinctrl: mediatek: add handling for RSEL register

2026-04-07T15:47:04Z

Add a new PINCTRL_PIN_REG_RSEL register type and a new function mtk_pinconf_bias_set_pu_pd_rsel() to handle setting it. Some MediaTek SoCs have a pin configuration register called RSEL that sets the resistance value for bias pullup/pulldown.

pinctrl: mediatek: Add missing bind callback for several SoCs

2026-03-24T16:10:27Z

Commit f4df9f53b7a9 ("pinctrl: mediatek: Bind gpio while binding pinctrl") refactored pinctrl-mtk-common.c and the SoC-specific drivers to register the gpiochip during the bind phase instead of probe. As part of this change, each SoC driver must implement a bind callback. The drivers recently added for mt8188, mt8189, mt8195 and mt8365 do not define this callback, which prevents the gpiochip from being registered properly. Add the missing bind callback to these drivers.
