Subject: [PATCH] dt-bindings: clock: Add a binding for the RPi
|
|
Firmware clocks
|
|
|
|
The firmare running on the RPi VideoCore can be used to discover and
|
|
change the various clocks running in the BCM2711. Since devices will
|
|
need to use them through the DT, let's add a pretty simple binding.
