pinctrl: mediatek: enable module build support for all SoC drivers

2026-07-27T09:11:13Z

Convert the Kconfig option of every MediaTek pinctrl SoC driver from bool to tristate and add MODULE_DESCRIPTION()/MODULE_LICENSE() so that they can be built as loadable kernel modules. This is required for Android GKI + vendor_dlkm deployments, where vendor-specific drivers must be kept separate from the GKI vmlinux and loaded as modules from the vendor partition.

pinctrl: mediatek: allow common drivers to be built as modules

2026-07-25T12:57:35Z

The MediaTek SoC pinctrl drivers link against the shared implementations in pinctrl-mtk-common.c (v1), pinctrl-moore.c and pinctrl-mtmips.c. These were built-in only: their Kconfig symbols were bool, they did not export their entry points and they carried no MODULE_LICENSE(). To let the individual SoC drivers be built as loadable modules (required for Android GKI + vendor_dlkm, where vendor drivers must live outside the GKI vmlinux), the shared code they depend on has to be modular too. Otherwise selecting a SoC driver as =m forces the common symbol to =y and the resulting module fails to link against the unexported common entry points. Convert PINCTRL_MTK, PINCTRL_MTK_MOORE and PINCTRL_MTK_MTMIPS to tristate, export the entry points used by the SoC drivers, and add MODULE_DESCRIPTION()/MODULE_LICENSE() to the three common files. The v2 common code (PINCTRL_MTK_V2) is already modular, but mtk_rmw() was never exported. It is called directly by SoC drivers such as mt7623, so export it as well to keep those drivers linking once they are modular. Rather than exporting these shared symbols into the global namespace, export them in the "MTK_PINCTRL" symbol namespace with EXPORT_SYMBOL_NS_GPL() so they are only visible to drivers that opt in. Each SoC driver that uses them therefore declares MODULE_IMPORT_NS("MTK_PINCTRL"). Signed-off-by: Justin Yeh Reviewed-by: AngeloGioacchino Del Regno Signed-off-by: Linus Walleij

pinctrl: Move Airoha driver to dedicated directory

2026-06-08T08:15:16Z

In preparation for additional SoC support, move the Airoha pinctrl driver for AN7581 SoC to a dedicated directory. This is to tidy things up and keep code organized without polluting the Mediatek driver directory. The driver doesn't depend on any generic or common code from the Mediatek codebase so it can be safely moved without any modification.
