In prepare_function_table() when the pinctrl function table IRQ entries are generated, the pin bank is calculated from the absolute pin number; however the IRQ bank mux array is indexed from the first pin bank of the controller. For R_PIO controllers, this means the absolute pin bank is way off from the relative pin bank used for array indexing. Correct this by taking into account the pin base of the controller.

2025-05-21pinctrl: freescale: Add support for imx943 pinctrlJacky Bai
The i.MX943 System Manager (SM) firmware supports the System Control Management Interface (SCMI) pinctrl protocol, similar to the i.MX95 SM. The base offset for the i.MX943 IOMUXC Daisy input register differs from that of the i.MX95. Update the pinctrl-imx-scmi driver to add support for i.MX943.

2025-05-21pinctrl: mediatek: eint: Fix invalid pointer dereference for v1 platformsNícolas F. R. A. Prado
Commit 3ef9f710efcb ("pinctrl: mediatek: Add EINT support for multiple addresses") introduced an access to the 'soc' field of struct mtk_pinctrl in mtk_eint_do_init() and for that an include of pinctrl-mtk-common-v2.h. However, pinctrl drivers relying on the v1 common driver include pinctrl-mtk-common.h instead, which provides another definition of struct mtk_pinctrl that does not contain an 'soc' field. Since mtk_eint_do_init() can be called both by v1 and v2 drivers, it will now try to dereference an invalid pointer when called on v1 platforms. This has been observed on Genio 350 EVK (MT8365), which crashes very early in boot (the kernel trace can only be seen with earlycon). In order to fix this, since 'struct mtk_pinctrl' was only needed to get a 'struct mtk_eint_pin', make 'struct mtk_eint_pin' a parameter of mtk_eint_do_init() so that callers need to supply it, removing mtk_eint_do_init()'s dependency on any particular 'struct mtk_pinctrl'.

2025-05-16pinctrl: Switch to irq_domain_create_*()Jiri Slaby (SUSE)
irq_domain_add_*() interfaces are going away as being obsolete now. Switch to the preferred irq_domain_create_*() ones. Those differ in the node parameter: They take more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the original parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).
