pinctrl: gpio: vt8500: Add pincontrol driver for arch-vt8500 This patch adds support for the GPIO/pinmux controller found on the VIA VT8500 and Wondermedia WM8xxx-series SoCs. Each pin within the controller is capable of operating as a GPIO or as an alternate function. The pins are numbered according to their control bank/bit so that if new pins are added, the existing numbering is maintained. All currently supported SoCs are included: VT8500, WM8505, WM8650, WM8750 and WM8850.

pinctrl: vt8500: make bool drivers explicitly non-modular None of the Kconfigs for any of these drivers are tristate, meaning that they currently are not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the drivers there is no doubt they are builtin-only. All drivers get the exact same change, so they are handled in batch. Changes are (1) use builtin_platform_driver, (2) use init.h header (3) delete module_exit related code, (4) delete MODULE_DEVICE_TABLE, (5) delete MODULE_LICENCE/MODULE_AUTHOR and associated tags and (6) drop ".remove" code and prevent sysfs unbind attempts to call ".remove". Once this is done, the shared remove function in wmt.[ch] is no longer used and hence it is removed as well. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE etc. tags since all that information is already contained at the top of each file in the comments.

Each pin within the controller is capable of operating as a GPIO or as an alternate function. The pins are numbered according to their control bank/bit so that if new pins are added, the existing numbering is maintained. All currently supported SoCs are included: VT8500, WM8505, WM8650, WM8750 and WM8850.

Once this is done, the shared remove function in wmt.[ch] is no longer used and hence it is removed as well.

pinctrl: gpio: vt8500: Add pincontrol driver for arch-vt8500 This patch adds support for the GPIO/pinmux controller found on the VIA VT8500 and Wondermedia WM8xxx-series SoCs. Each pin within the controller is capable of operating as a GPIO or as an alternate function. The pins are numbered according to their control bank/bit so that if new pins are added, the existing numbering is maintained. All currently supported SoCs are included: VT8500, WM8505, WM8650, WM8750 and WM8850.
