Qualcomm Technologies, Inc. WCD audio CODEC

PM5100 SPMI node

pm5100_spmi: Child node of SPMI bus required for besbev codec
	     in order to access SPMI register to reset the peripheral.

Required properties:
 -compatible: "qcom,pm5100-spmi";

&spmi_bus {
	pm5100_cdc: qcom,pm5100-cdc {
	compatible = "qcom,pm5100-spmi";
	};
};

Besbev Codec

Required properties:
 - compatible: "qcom,besbev-codec";
 - qcom,split-codec: Property to check on split codec support.
 - qcom,swr_ch_map: mapping of swr tx/rx slave port configuration to port_type and also
		corresponding master port type it need to attach.
		format: <port_id, slave_port_type, ch_mask, ch_rate, master_port_type>
		same port_id configurations have to be grouped, and in ascending order.
 - qcom,pmic-spmi-node: Phandle reference to the PMIC SPMI DT node.
 - qcom,wcd-reset-reg: Reset register address in PMIC for rouleur codec.
 - qcom,besbev-slave: phandle reference of Soundwire Tx/Rx slave device.
 - qcom,speaker-present: Property to check besbev is connected RX SWR or TX SWR of bolero codec.

Optional properties:

 - cdc-mic-bias-supply: phandle of mic bias supply's regulator device tree node.
 - qcom,cdc-mic-bias-voltage: mic bias supply's voltage level min and max in mV.
 - qcom,cdc-mic-bias-current: mic bias supply's max current in mA.

 - qcom,cdc-mic-bias-lpm-supported: mic bias supply's LPM mode.

 - qcom,cdc-static-supplies: List of supplies to be enabled prior to codec
			     hardware probe.  Supplies in this list will be
			     stay enabled.
