Subject: [PATCH 1/2] dmaengine: Extend the dmaengine_alignment for 128 and 256 bytes
Date: Mon, 14 Dec 2020 10:13:09 +0200	[thread overview]
Message-ID: <20201214081310.10746-2-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <20201214081310.10746-1-peter.ujfalusi@ti.com>

Some DMA device can benefit with higher order of alignment than the maximum
of 64 bytes currently defined.

Define 128 and 256 bytes alignment for these devices.
