Subject: [PATCH v2 2/3] crypto: sa2ul: Support for per channel coherency
Date: Tue, 13 Apr 2021 14:45:58 +0530 [thread overview]
Message-ID: <20210413091559.154169-3-vaibhavgupta40@gmail.com> (raw)
In-Reply-To: <20210413091559.154169-1-vaibhavgupta40@gmail.com>
From: Peter Ujfalusi <peter.ujfalusi@ti.com>
On AM64 the DMA channel for sa2ul can be configured to be coherent or
non coherent via DT binding.
Use the dmaengine_get_device_for_dma_api() to get the device pointer which
should be used for with the dma_api to use matching dma_ops for the
channel coherency/non coherency.
