[PATCH 06/89] dt-bindings: clock: Add a binding for the RPi Firmware clocks
From: Maxime Ripard <hidden>
Date: 2020-02-24 09:14:40
Also in:
dri-devel, linux-arm-kernel, linux-clk, lkml
Subsystem:
common clk framework, open firmware and flattened device tree bindings, the rest · Maintainers:
Michael Turquette, Stephen Boyd, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
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.
