+title: Device Tree Clock bindings for Calxeda highbank platform
+
+description: |
+ This binding covers the Calxeda SoC internal peripheral and bus clocks
+ as used by peripherals. The clocks live inside the "system register"
+ region of the SoC, so are typically presented as children of an
+ "hb-sregs" node.
