[PATCH 2/3] dt-bindings: Document Tegra264 HDA Support
Posted by Sheetal . 7 months, 1 week ago
From: Sheetal <sheetal@nvidia.com>

For Tegra264 device there is one clock, two resets and no power-domain.
Add the Tegra264 compatible and necessary logic to the binding doc to
determine appropriate clocks, resets and power-domain properties based
on the compatible string.
