pinctrl: mediatek: fix failing to get syscon

2026-01-21T19:30:55Z

Replace uclass_get_device_by_ofnode() with syscon_regmap_lookup_by_phandle() to get the "mediatek,pctl-regmap" syscon device. Depending on probe order, uclass_get_device_by_ofnode() may fail, but syscon_regmap_lookup_by_phandle() has logic in it to handle that case correctly. The previous implementation could read more than one syscon if the "mediatek,pctl-regmap" property had more than one phandle, but the one board with a devicetree that does that is not supported in U-Boot yet, so we can save that for later (it may never be needed).

pinctrl: mediatek: ignored error return from pupd/r1/r0

2026-01-21T19:29:28Z

Ignore the error return value from mtk_pinconf_bias_set_pupd_r1_r0(). The PUPD/R1/R0 registers only include a small subset of the pins, so it is normal for this function to return an error for most pins. Therefore, this error should not be propagated. This fixes not all pins in a pinmux group being configured in some cases because the propagated error caused the configuration loop to exit early. The rest of the function is refactored to return early on errors to improve readability. Signed-off-by: David Lechner

pinctrl: mediatek: set array size for reg_cals

2026-01-21T19:29:25Z

Set the size of the reg_cals arrays to PINCTRL_PIN_REG_MAX to in all affected mediatek pinctrl drivers. This is needed to avoid potential out-of-bounds accesses when they is used in mtk_hw_pin_field_get(). All array members need to be initialized since the code loops from 0 to PINCTRL_PIN_REG_MAX - 1. mt7622_reg_cals was already defined this way, but the others were not. Signed-off-by: David Lechner

pinctrl: qcom: add PINCTRL_QCOM_GENERIC to enable all drivers by default

2026-01-14T15:25:09Z

Introduce a new Kconfig option PINCTRL_QCOM_GENERIC that, when selected, enables all Qualcomm pinctrl drivers by default. This simplifies defconfigs for platforms supporting multiple SoCs and avoids manual driver selection. Individual drivers can still be disabled if required.

Merge patch series "pinctl: mediatek: add mt8365 support"

2026-01-12T19:41:54Z

David Lechner says: MT8365 has different pinctrl register layout compared to other SoCs in the family, so needs its own driver. This is also the first SoC in this family supported in U-Boot using an upstream devicetree that has the mediatek,pctl-regmap property, so we need to add support for that to the common mediatek pinctrl code first.
