Subject: [PATCH 06/89] dt-bindings: clock: Add a binding for the RPi Firmware clocks
Date: Mon, 24 Feb 2020 10:06:08 +0100 [thread overview]
Message-ID: <9166f3acdc2a64e3f3ca1cd2e283005ee2df37c9.1582533919.git-series.maxime@cerno.tech> (raw)
In-Reply-To: <cover.6c896ace9a5a7840e9cec008b553cbb004ca1f91.1582533919.git-series.maxime@cerno.tech>
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.
