[PATCH] dt-bindings: crypto: ti,sa2ul: drop dma-coherent property

[Jayesh Choudhary]

crypto driver itself is not dma-coherent. It is the dmaengine
that moves data and the buffers are to be mapped to the
dmaengine provider. So this property should be dropped.

Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.

Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

These warnings are expected. dt-node fixes need to be there.
I will send the dt-node fixes once this patch gets in due to
dependency. Or should I proceed any other way?

Thanks,

This patch is ACKed and there are no other comments.
Can this patch be merged so that I can move forward with dt node
fixes or do you have any other comments on this?

Regards,
Jayesh
