that indicates the coherency of the IP. The PRUSS IPs on 66AK2G
SoCs do use this property.

Hi Santosh,
This patch updates the PRUSS binding in preparation for adding the
PRUSS nodes for 66AK2G SoCs. Without this, the dtbs_check would
complain about the undefined dma-coherent property. Patch is top
of the AM64 ICSSG binding update patch [1].
regards
Suman

New required properties are not backwards compatible. You are kind of
saying that here (not used yet?), but make that clear in the commit msg.
With that fixed,

OK. Yeah, we haven't added the K2G dts nodes yet, and the new required property
is only applicable for that SoC and not others.
