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.

NVIDIA Tegra audio complex
|
|
|
|
Required properties:
|
|
- compatible : "nvidia,tegra-audio-wm9712"
|
|
- clocks : Must contain an entry for each entry in clock-names.
|
|
See ../clocks/clock-bindings.txt for details.
|
|
- clock-names : Must include the following entries:
|
|
- pll_a
|
|
- pll_a_out0
|
|
- mclk (The Tegra cdev1/extern1 clock, which feeds the CODEC's mclk)
|
|
- nvidia,model : The user-visible name of this sound complex.
|
|
- nvidia,audio-routing : A list of the connections between audio components.
|
|
Each entry is a pair of strings, the first being the connection's sink,
|
|
the second being the connection's source. Valid names for sources and
|
|
sinks are the WM9712's pins, and the jacks on the board:
