From 6e40dfa0220e68a6628d9e7d18788df6bcae5473 Mon Sep 17 00:00:00 2001 From: Nick Brassel Date: Mon, 27 Dec 2021 11:52:10 +1100 Subject: Add open-drain GPIO support. (#15282) * Add open-drain GPIO support. * `qmk format-c` * Wording. * Remove port GPIO implementations as the only board that uses it has its own internal defs anyway.
