+
+ SerDes is a serializer/deserializer used by some Freescale SoC.
+
+ Required properties:
+
+ - compatible : Should specify what this SerDes controller is compatible
+ with. Currently, this is most likely to be "fsl,serdes".
+ - reg : Offset and length of the register set for the device.
+ - protocol : Which up layer protocol is running on the serial
+ interface. Could be "sata", "pcie", "sgmii".
+ - clock : Input clock frequency for SerDes in unit of MHz.
+
+ Optional properties:
+
+ - vdd-1v : Define this property when Vdd is 1V.
+ - pcie-x2 : Define this property when using PCI Express x2 interface.
+ Valid only when protocol is set to "pcie".
+
+ Example:
+
+ serdes1:[EMAIL PROTECTED] {
+ compatible = "fsl,serdes";
+ reg = <e3000 100>;
+ vdd-1v;
+ protocol = "sata";
+ clock = <d#100>;
+ };
+
More devices will be defined as this spec matures.
