Subject: [PATCH 02/19] iommu/arm-smmu-v3: support ops registration for CDX bus
Date: Tue, 17 Jan 2023 19:11:34 +0530	[thread overview]
Message-ID: <20230117134139.1298-3-nipun.gupta@amd.com> (raw)
In-Reply-To: <20230117134139.1298-1-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.
