Subject: [PATCH v2 5/6] arm64: dts: allwinner: a64: Update MBUS node
Date: Sun,  3 Oct 2021 20:27:38 -0500	[thread overview]
Message-ID: <20211004012739.39053-6-samuel@sholland.org> (raw)
In-Reply-To: <20211004012739.39053-1-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.
