* Freescale Asynchronous Sample Rate Converter (ASRC)

This document is for asrc p2p node. p2p is one of asrc mode. asrc p2p depend on
MXC_ASRC.

Required properties:
  - compatible: Should be "fsl,<chip>-asrc-p2p".
  - fsl,p2p-rate: the p2p rate of asrc p2p. which can be <32000> to <192000>,
  - fsl,p2p-width: the p2p width of asrc p2p. which can be <16>, <24>.
  - fsl,asrc-dma-rx-events: The rx dma event of the asrc, <a b c> corresponding
			    to 3 pair of asrc.
  - fsl,asrc-dma-tx-events: The tx dma event of the esai, <a b c> corresponding
			    to 3 pair of asrc.

Example:
asrc_p2p: asrc_p2p {
	compatible = "fsl,imx6q-asrc-p2p";
	fsl,p2p-rate  = <48000>;
	fsl,p2p-width = <16>;
	fsl,asrc-dma-rx-events = <17 18 19>;
	fsl,asrc-dma-tx-events = <20 21 22>;
	status = "okay";
};
