Subject: [PATCH v3 5/6] arm64: dts: allwinner: a64: Update MBUS node
Date: Wed, 17 Nov 2021 21:18:40 -0600 [thread overview]
Message-ID: <20211118031841.42315-6-samuel@sholland.org> (raw)
In-Reply-To: <20211118031841.42315-1-samuel@sholland.org>
In order to support memory dynamic frequency scaling (MDFS), the MBUS
binding now requires enumerating more resources. Provide them in the
device tree.
