Subject: [PATCH 2/4] ARM: dma: define DMA_ALIGNMENT instead of defining dma_alloc
Date: Thu, 21 Sep 2023 11:56:47 +0200 [thread overview]
Message-ID: <20230921095649.310666-2-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20230921095649.310666-1-a.fatoum@pengutronix.de>
There's a suitable fallback dma_alloc implementation already in dma.h,
which we can use as soon as we define DMA_ALIGNMENT. By doing that, we
also can use the __dma_aligned attribute that will come in handy in the
follow-up commit.
