Subject: dt-bindings: Document Tegra264 HDA Support
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=3bc2f3ba7b4d81523f89dfa369edb56507bd63e6;p=users%2Fdwmw2%2Flinux.git

dt-bindings: Document Tegra264 HDA Support

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.
