SIUL2 is now represented as an mfd device. Therefore, the old pinctrl node is deprecated. Move the pinctrl related properties inside the new "nxp-siul2" node. The latter one is now used to represent the mfd device. This change came as a result of upstream review in the following series: https://lore.kernel.org/linux-gpio/a924bbb6-96ec-40be-9d82-a76b2ab73afd@xxxxxxxxxxx/ https://lore.kernel.org/all/20240926143122.1385658-3-andrei.stefanescu@xxxxxxxxxxx/ The SIUL2 module has multiple capabilities. It has support for reading SoC information, pinctrl and GPIO. All of this functionality is part of the same register space. The initial pinctrl driver treated the pinctrl functionality as separate from the GPIO one. However, they do rely on common registers and a long, detailed and specific register range list would be required for pinctrl&GPIO (carving out the necessary memory for each function). Moreover, in some cases this wouldn't be enough. For example reading a GPIO's direction would require a read of the MSCR register corresponding to that pin. This would not be possible in the GPIO driver because all of the MSCR registers are referenced by the pinctrl driver.
