Subject: [PATCH 1/2] dt-bindings: tegra: pmc: Update aotag as an optional aperture
Date: Fri, 14 Nov 2025 16:17:10 +0000	[thread overview]
Message-ID: <20251114161711.2655355-1-jonathanh@nvidia.com> (raw)

Not all Tegra SoCs or all versions of a particular Tegra SoC may include
the AOTAG aperture. This change makes "aotag" as an optional aperture for
Tegra234 and Tegra264.

Admittedly I don't know if there is a better way to handle this,
but if there is please let me know!
