[PATCH v2 3/4] arm64: dts: ti: k3-am65: mark dss as dma-coherent

[Tomi Valkeinen]

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

[PATCH v2 4/4] arm64: dts: ti: am654-base-board: fix clock node name

[Tomi Valkeinen]

The fixed clock for OV5640 is named 'clock' which is a very generic name
and easily leads to conflicts. I encountered this with a similarly named
fixed-clock node in k3-am654-evm-tc358876.dtso, which then overrode the
OV5640 fixed clock, causing OV5640 not to work when tc358876 overlay had
been loaded.

Rename the node to 'fixed-clock-ov5640'.

Looks fine to me. Once you get the bindings in to next, we can look to
get the dts in.
