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.
