the audio subsystem and use it to play a vibration. Add a binding
document for it.

 - reg: Specifies the haptics soundwire slave unique device address.

 - swr-slave-supply: Specify the phandle of the regulator device to take

		haptics soundwire slave out of reset.

 - qcom,rx_swr_ch_map: Specify the mapping of soundwire rx slave port configuration.

		format: <port_id, ch_mask, ch_rate, num_ch, port_type>.



Example:

swr_haptics: swr_haptics@f0170220 {

	compatible = "qcom,pm8350b-swr-haptics";

	reg = <0x01 0xf0170220>;
