1 | NVIDIA Tegra audio complex |
2 | ||
3 | Required properties: | |
4 | - compatible : "nvidia,tegra-audio-wm8903" | |
f9cd2b3b | 5 | - clocks : Must contain an entry for each entry in clock-names. |
d8f64797 | 6 | See ../clocks/clock-bindings.txt for details. |
f9cd2b3b | 7 | - clock-names : Must include the following entries: |
d8f64797 SW |
8 | - pll_a |
9 | - pll_a_out0 | |
10 | - mclk (The Tegra cdev1/extern1 clock, which feeds the CODEC's mclk) | |
07cdf36d SW |
11 | - nvidia,model : The user-visible name of this sound complex. |
12 | - nvidia,audio-routing : A list of the connections between audio components. | |
13 | Each entry is a pair of strings, the first being the connection's sink, | |
14 | the second being the connection's source. Valid names for sources and | |
