=====================================================================
Introduction

The PQ-MDS-T1 -	A board card with the T1/E1/DS3/T3/SLIC-SLAC module
		which serves as a platform for S/W and H/W development
		around the host device, it is connected by PMC sockets.

1.TDM PHY
	Function : DS26528 T1/E1/J1 transceiver

Properties
  - compatible
	Usage: required
	Value type: <string>
	Definition: Should be "fsl,pq-mds-t1".
  - reg
	Usage: required
	Value type: <prop-encoded-array>
	Definition: The first reg specifier describes the the address,
		and the second describes the length.
  - line-rate
	Usage: required
	Value type: <string>
	Definition: It descrbets the line rate "e1" or "t1". "e1" is 2.048MHz
		"t1" is 1.544MHz.
  - fsl,trans-mode
	Usage: required
	Value type: <string>
	Definition: TDM controller transfer mode setting
		Normal operation: set fsl,trans-mode = "normal". In this mode,
			controller sends and receives data normally.
		Loopback operation: set fsl,trans-mode = "internal-loopback".
			In this mode, the data is sent via tsa tx pin and
			received from tsa rx pin.
Example

	ds26528: tdm-phy@0 {
		compatible = "dallas,ds26528";
		reg = <0 0x2000>;
		line-rate = "e1";
		fsl,trans-mode = "normal";
	};

2.PQ-MDS-T1 PLD
	Function: Board identification, control and clock/signal routing

Properties
  - fsl,card-support
	Usage: required
	Value type: <u32>
	Definition: This property use phandle to describe which it serves as,
		ds26528 or zarlink.

Example
	pld-reg@2000 {
		compatible = "fsl,pq-mds-t1-pld";
		reg = <0x2000 0x1000>;
		fsl,card-support = <&ds26528>;
	}
