Subject: [PATCH V2 6/8] dmaengine: zynqmp_dma: Use of_dma_is_coherent for dma-coherent
Date: Fri, 14 Aug 2026 10:26:14 +0530 [thread overview]
Message-ID: <20260814045616.1661199-7-nagendra.golla@amd.com> (raw)
In-Reply-To: <20260814045616.1661199-1-nagendra.golla@amd.com>
Use of_dma_is_coherent() instead of parsing the common dma-coherent
device-tree property directly.
Signed-off-by: Golla Nagendra <nagendra.golla@amd.com>

changes in v2:
- Added as a dedicated patch based on review feedback to use of_dma_is_coherent()
for the common dma-coherent property
