Subject: [PATCH v4 1/7] clk: bcm2835: remove pllb
Date: Wed, 12 Jun 2019 20:24:53 +0200	[thread overview]
Message-ID: <20190612182500.4097-2-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20190612182500.4097-1-nsaenzjulienne@suse.de>

Raspberry Pi's firmware controls this pll, we should use the firmware
interface to access it.
