Subject: [PATCH] dt-bindings: soc: ti: pruss: Add dma-coherent property
Date: Thu, 29 Jul 2021 22:19:01 -0500	[thread overview]
Message-ID: <20210730031901.26243-1-s-anna@ti.com> (raw)

Update the PRUSS schema file to include the dma-coherent property
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
