Subject: [PATCH v2] arm64: dts: ti: k3-am65: mark dss as dma-coherent
Date: Mon, 2 Nov 2020 15:46:50 +0200	[thread overview]
Message-ID: <20201102134650.55321-1-tomi.valkeinen@ti.com> (raw)

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

Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
Fixes: fc539b90eda2 ("arm64: dts: ti: am654: Add DSS node")
Cc: stable@vger.kernel.org # v5.8+
Acked-by: Nikhil Devshatwar <nikhil.nd@ti.com>
---

v2: Added fixes, stable and Nikhil's ack.
