Subject[PATCH 5.10 595/717] arm64: dts: ti: k3-am65: mark dss as dma-coherent
Date
From: Tomi Valkeinen <tomi.valkeinen@ti.com>

commit 50301e8815c681bc5de8ca7050c4b426923d4e19 upstream.

DSS is IO coherent on AM65, so we should mark it as such with
'dma-coherent' property in the DT file.

Fixes: fc539b90eda2 ("arm64: dts: ti: am654: Add DSS node")
