Subject: [PATCH v9 2/7] iommu: Support ops registration for CDX bus
Date: Tue, 7 Mar 2023 18:49:12 +0530	[thread overview]
Message-ID: <20230307131917.30605-3-nipun.gupta@amd.com> (raw)
In-Reply-To: <20230307131917.30605-1-nipun.gupta@amd.com>

With new CDX bus supported for AMD FPGA devices on ARM
platform, the bus requires registration for the SMMU v3
driver.
