Subject[PATCH 5.10 087/105] ARM: tegra: Move panels to AUX bus
Date
From: Thierry Reding <treding@nvidia.com>

[ Upstream commit 8d3b01e0d4bb54368d73d0984466d72c2eeeac74 ]

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.

Fixes: eb481f9ac95c ("ARM: tegra: add Acer Chromebook 13 device tree")
Fixes: 59fe02cb079f ("ARM: tegra: Add DTS for the nyan-blaze board")
Fixes: 40e231c770a4 ("ARM: tegra: Enable eDP for Venice2")
