Many of the Tegra DT binding documents say nothing about the clocks or clock-names properties, yet those are present and required in DT files. This patch simply updates the documentation file to match the implicit definition of the binding, based on real-world DT content. All Tegra bindings that mention clocks are updated to have consistent wording and formatting of the clock-related properties.

|
|
Required properties:
|
|
- compatible : "nvidia,tegra-audio-wm9712"
|
|
- clocks : Must contain an entry for each entry in clock-names.
|
