From: rmk+kernel@arm.linux.org.uk (Russell King) Date: Thu, 01 Aug 2013 22:58:09 +0100 Subject: [PATCH RFC 24/51] DMA-API: dma: pl330: add dma_set_mask_and_coherent() call In-Reply-To: <20130801213420.GL23006@n2100.arm.linux.org.uk> References: <20130801213420.GL23006@n2100.arm.linux.org.uk> Message-ID: To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The DMA API requires drivers to call the appropriate dma_set_mask() functions before doing any DMA mapping. Add this required call to the AMBA PL08x driver.
