From 7518f6fbc4b9f786dabef4ada2881024a2039bb9 Mon Sep 17 00:00:00 2001 From: Mikhail Kshevetskiy Date: Fri, 3 Jul 2026 14:56:19 +0300 Subject: pinctrl: add more pinconf/pinctrl definitions These pinconf/pinctrl definitions will be used by the next patches. The definitions was taken from public headers of linux-7.0. It's used by several linux pinctrl drivers, so it might be helpful for U-Boot as well. Pinconf definitions are placed near the corresponding U-Boot definitions in file include/dm/pinctrl.h. Pin/group/function definitions stored within the same path as in linux (include/linux/pinctrl/pinctrl.h).
