+Micrel PHY properties.
+
+These properties cover the base properties Micrel PHYs.
+
+Optional properties:
+
+ - micrel,led-mode : LED mode value to set for PHYs with configurable LEDs.
+
+       Configure the LED mode with single value. The list of PHYs and the
+       bits that are currently supported:
+
+       KSZ8001: register 0x1e, bits 15..14
+       KSZ8041: register 0x1e, bits 15..14
+       KSZ8021: register 0x1f, bits 5..4
+       KSZ8031: register 0x1f, bits 5..4
+       KSZ8051: register 0x1f, bits 5..4
+       KSZ8081: register 0x1f, bits 5..4
+       KSZ8091: register 0x1f, bits 5..4
+
+       See the respective PHY datasheet for the mode values.
+
+ - micrel,rmii-reference-clock-select-25-mhz: RMII Reference Clock Select
+                                               bit selects 25 MHz mode
+
+       Setting the RMII Reference Clock Select bit enables 25 MHz rather
+       than 50 MHz clock mode.
+
+       Note that this option in only needed for certain PHY revisions with a
+       non-standard, inverted function of this configuration bit.
+       Specifically, a clock reference ("rmii-ref" below) is always needed to
+       actually select a mode.
+
+ - clocks, clock-names: contains clocks according to the common clock bindings.
+
+       supported clocks:
+       - KSZ8021, KSZ8031, KSZ8081, KSZ8091: "rmii-ref": The RMII reference
+         input clock. Used to determine the XI input clock.
