Subject: [PATCH] dmaengine: dw-edma: Add HDMA NATIVE map check
Date: Tue, 8 Apr 2025 11:56:04 +0530 [thread overview]
Message-ID: <20250408062604.2809548-1-devverma@amd.com> (raw)
The HDMA IP supports the HDMA_NATIVE map format as part of Vendor-Specific
Extended Capability. Added the check for HDMA_NATIVE map format.
The check for map format enables the IP specific function invocation
during the DMA ops.
