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.
Signed-off-by: Suman Anna <s-anna@ti.com>

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
