- compatible = "qcom,msm-sdw-codec";
- reg: Specifies the soundwire codec base address for MSM digital
soundwire core registers.
- interrupts: Specifies the soundwire master interrupt number to Apps processor.
- interrupt-names: Specify the interrupt name from soundwire master.
- swr_master: This node is added as a child of MSM soundwire codec
and uses already existing driver soundwire master.
And there is/are subchild node(s) under soundwire master
which is also existing driver WSA881x that represents
soundwire slave devices.
Example:
msm_sdw_codec: qcom,msm-sdw-codec@152c1000 {
compatible = "qcom,msm-sdw-codec";
reg = <0x152c1000 0x0>;
interrupts = <0 161 0>;
interrupt-names = "swr_master_irq";
swr_master {
compatible = "qcom,swr-wcd";
#address-cells = <2>;
#size-cells = <0>;
wsa881x_1: wsa881x@20170212 {
compatible = "qcom,wsa881x";
reg = <0x00 0x20170212>;
qcom,spkr-sd-n-gpio = <&tlmm 80 0>;
};
};
};
Tasha audio CODEC in I2C mode
