Subject: [U-Boot] [PATCH 1/4] topic-miamiplus: Run CPU at 800MHz for speedgrade-2
Date: Fri, 24 Aug 2018 14:00:38 +0200	[thread overview]
Message-ID: <1535112041-1563-2-git-send-email-mike.looijmans@topic.nl> (raw)
In-Reply-To: <1535112041-1563-1-git-send-email-mike.looijmans@topic.nl>

The miamiplus contains a speedgrade-2 device, which may run the CPU at 800MHz.
Change the PLL setting to 800MHz, and adapt the setpoints in the devicetree.
