From a41315610bab6f152280975500f33e3b069e10ff Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Thu, 6 Aug 2020 17:41:08 +0200 Subject: [PATCH] arm64: tegra: Wire up pinctrl states for all DPAUX controllers All four DPAUX controllers on Tegra194 control the pin configuration of their companion I2C controllers. Wire up all the pinctrl states for the I2C controllers so that their pins can be correctly muxed when needed.
