From a7a3de5edb142c7cefdb6e810cc07a6222f7541d Mon Sep 17 00:00:00 2001 From: Lech Perczak Date: Tue, 7 Mar 2023 01:14:05 +0100 Subject: [PATCH] ath79: fix user LED glow on Mikrotik 911 Lite boards GPIO3, to which the user LED is connected on RB911-Lite boards seems to still sink current, even when driven high. Enabling open drain for this pin fixes this behaviour and gets rid of the glow when LED is set to off, so enable it.
