[PATCH 10/10] arm64: dts: ti: k3-am62: Enable OSPI nodes at the board level
From: Andrew Davis
Date: Tue Oct 18 2022 - 17:16:41 EST
OSPI nodes defined in the top-level AM62x SoC dtsi files are incomplete
and will not be functional unless they are extended with pinmux
information.
As the pinmux is only known at the board integration level, these
nodes should only be enabled when provided with this information.
Disable the OSPI nodes in the dtsi files and only enable the ones that
are actually pinned out on a given board.
