Subject: [PATCH 3/4] arm64: dts: ti: k3-am65: mark dss as dma-coherent
Date: Tue, 27 Oct 2020 12:41:31 +0200 [thread overview]
Message-ID: <20201027104132.105485-4-tomi.valkeinen@ti.com> (raw)
In-Reply-To: <20201027104132.105485-1-tomi.valkeinen@ti.com>
DSS is IO coherent on AM65, so we can mark it as such with
'dma-coherent' property in the DT file.
