Subject: [PATCH 3/8] dmaengine: dw-edma: Use new .device_prep_slave_sg_config() callback
Date: Mon, 08 Dec 2025 12:09:42 -0500	[thread overview]
Message-ID: <20251208-dma_prep_config-v1-3-53490c5e1e2a@nxp.com> (raw)
In-Reply-To: <20251208-dma_prep_config-v1-0-53490c5e1e2a@nxp.com>

Use the new .device_prep_slave_sg_config() callback to combine
configuration and descriptor preparation.

No functional changes.
