Subject: [PATCH 2/2] ARM: tegra: Move panels to AUX bus
Date: Mon, 20 Dec 2021 11:48:55 +0100 [thread overview]
Message-ID: <20211220104855.428290-3-thierry.reding@gmail.com> (raw)
In-Reply-To: <20211220104855.428290-1-thierry.reding@gmail.com>
From: Thierry Reding <treding@nvidia.com>
Move the eDP panel on Venice 2 and Nyan boards into the corresponding
AUX bus device tree node. This allows us to avoid a nasty circular
dependency that would otherwise be created between the DPAUX and panel
nodes via the DDC/I2C phandle.
