Subject: [PATCH v6 2/7] iommu/arm-smmu-v3: support ops registration for CDX bus
Date: Thu, 26 Jan 2023 16:16:25 +0530 [thread overview]
Message-ID: <20230126104630.15493-3-nipun.gupta@amd.com> (raw)
In-Reply-To: <20230126104630.15493-1-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.
