Subject: [RFC v2 4/5] dts: bcm2837: add per-cpu clock devices
Date: Mon, 20 May 2019 12:47:06 +0200
Message-ID: <20190520104708.11980-5-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20190520104708.11980-1-nsaenzjulienne@suse.de>
The four CPUs share a same clock source called pllb_arm. The clock can
be scaled through the raspberrypi firmware interface.
