Subject: [PATCH 1/4] arm64: tegra: Wire up pinctrl states for all DPAUX controllers
Date: Thu, 6 Aug 2020 17:41:08 +0200 [thread overview]
Message-ID: <20200806154111.3917284-1-thierry.reding@gmail.com> (raw)
From: Thierry Reding <treding@nvidia.com>
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.
