of how to define a PHY.
Required properties:
- - reg : Offset and length of the register set for the device
+ - reg : Offset and length of the register set for the device, and optionally
+ the offset and length of the TBIPA register (TBI PHY address
+ register). If TBIPA register is not specified, the driver will
+ attempt to infer it from the register set specified (your mileage may
+ vary).
- compatible : Should define the compatible device type for the
mdio. Currently supported strings/devices are:
- "fsl,gianfar-tbi"
device_type = "mdio";
#address-cells = <1>;
#size-cells = <0>;
- reg = <0x0 0x2d24000 0x0 0x4000>;
+ reg = <0x0 0x2d24000 0x0 0x4000>,
+ <0x0 0x2d10030 0x0 0x4>;
