Subject: [PATCH v2 3/4] arm64: dts: ti: k3-am65: mark dss as dma-coherent
Date: Thu, 27 Aug 2020 11:30:44 +0300 [thread overview]
Message-ID: <20200827083045.76356-3-tomi.valkeinen@ti.com> (raw)
In-Reply-To: <20200827083045.76356-1-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.
