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.
