Subject: [PATCH v2 00/11] PCI/ATS: Device-tree support and other improvements
Date: Wed, 11 Mar 2020 13:44:55 +0100 [thread overview]
Message-ID: <20200311124506.208376-1-jean-philippe@linaro.org> (raw)
Enable ATS on device-tree based systems, and factor the common ATS
enablement checks into pci_enable_ats().
Since v1 [1] I added acks and review tags, simplified patch 3 and tried
to clarify the comment in patch 2.
I'd like acks or comments on the following patches:
* PCI on patches 2, 3 and 5
* Arm SMMUv3 on patch 7
* Intel VT-d on patch 8
* arm64 DT on patch 10
Thanks,
Jean
