From 564237a602e1c8cf60bea58c34dcb7a0a15466c8 Mon Sep 17 00:00:00 2001 From: Abdelatif Guettouche Date: Mon, 5 Oct 2020 10:54:48 +0100 Subject: [PATCH] arch/xtensa/src/esp32/esp32_gpio: Function "SPECIAL" doesn't exist. All pads go through the same GPIO matrix to select one of the 6 possible functions.
