As suggested in reviews the requirement of clocks in the 'sound' node is dropped and instead a leaf clock is used to configure frequency of the audio root clock PLL. This can work now after the clock tree definitions have been updated to allow clock rate setting propagation on the path from the I2S controller up to the EPLL. This patch also lowers the CODEC master clock frequency so as to not exceed the maximum allowed 60 MHz at maximum audio sampling rates.

|
|
property
|
|
- samsung,audio-widgets - this property specifies off-codec audio elements
|
|
like headphones or speakers, for details see widgets.txt
|
|
- samsung,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 MAX98090's pins (as
|
|
documented in its binding), and the jacks on the board
|
|
|
|
For Odroid X2:
|
|
"Headphone Jack", "Mic Jack", "DMIC"

For Odroid XU4:
|
|
no entries
|
|
|
|
Required sub-nodes:
|
|
|
|
- 'cpu' subnode with a 'sound-dai' property containing the phandle of the I2S
|
|
controller
|
|
- 'codec' subnode with a 'sound-dai' property containing list of phandles
|
|
to the CODEC nodes, first entry must be corresponding to the MAX98090
|
|
CODEC and the second entry must be the phandle of the HDMI IP block node
|
|
|
|
Example:
|
|
|
|
sound {
|
|
compatible = "samsung,odroidxu3-audio";
|
|
model = "Odroid-XU3";
|
|
samsung,audio-routing =
|
|
"Headphone Jack", "HPL",
|
|
"Headphone Jack", "HPR",
|
|
"IN1", "Mic Jack",
|
|
"Mic Jack", "MICBIAS";
|
|
|
|
cpu {
|
|
sound-dai = <&i2s0 0>;
|
|
};
|
|
codec {
|
|
sound-dai = <&hdmi>, <&max98090>;
|
|
};
|
|
};
