From 443a0a0f0cf4f432c7af6654b7f2f920d411d379 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 19 Dec 2022 14:42:33 +0200 Subject: [PATCH] pinctrl: Introduce struct pinfunction and PINCTRL_PINFUNCTION() macro There are many pin control drivers define their own data type for pin function representation which is the same or embed the same data as newly introduced one. Provide the data type and convenient macro for all pin control drivers.
