Subject: [PATCH V2 1/2] dt-bindings: tegra: pmc: Update aotag as an optional aperture
Date: Wed, 19 Nov 2025 09:37:28 +0000 [thread overview]
Message-ID: <20251119093729.441654-1-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.

Changes since V1:
- Simplified reg-names handling of optional aotag range by upon
Krzysztof's feedback.
- Dropped removal of reg modifications for tegra186 and tegra194.
- Updated reg minItems for tegra186.
