[PATCH v1 2/4] pinctrl: nuvoton: Make use of struct pinfunction and PINCTRL_PINFUNCTION()

From: Andy Shevchenko
Date: Tue Jun 11 2024 - 05:33:45 EST


From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>

Since pin control provides a generic data type and a macro for
the pin function definition, use them in the driver.
