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: mediatek: support mediatek,pctl-regmap property

2026-01-12T19:41:17Z

Add support for the mediatek,pctl-regmap devicetree property to the common MediaTek pinctrl driver. In upstream devicetrees from Linux, the pinctrl nodes may be on the interrupt controller register address space rather than the pinctrl register address space. In this case, there is a syscon node linking to the actual pinctrl registers. This uses a common property name of mediatek,pctl-regmap for the phandle to the syscon node. The logic here is that if this property is present, we look up the syscon node and use it's address as the base address of the pinctrl registers and ignore the pinctrl node's own reg property. (Support for interrupts could be added later if needed.) There is also at least one SoC in Linux that has two syscon phandles in this property. This implementation support parsing this, but doesn't do anything with the second syscon yet (the 2nd syscon is for interrupts which we are saving for later). Signed-off-by: David Lechner
