Subject: [RESEND PATCH v4 1/1] dt-bindings: arm-smmu: Add binding doc for Qcom smmu-500
Date: Thu, 13 Dec 2018 14:35:07 +0530 [thread overview]
Message-ID: <20181213090507.6269-1-vivek.gautam@codeaurora.org> (raw)
Qcom's implementation of arm,mmu-500 works well with current
arm-smmu driver implementation. Adding a soc specific compatible
along with arm,mmu-500 makes the bindings future safe.

Hi Joerg,
I am picking this out separately from the sdm845 smmu support
series [1], so that this can go through iommu tree.
The dt patch from the series [1] can be taken through arm-soc tree.
Hi Will,
As asked [2], here's the resend version of dt binding patch for sdm845.
Kindly ack this so that Joerg can pull this in.
Thanks
Vivek
