From 64113016a456399d3fe4849a4f6593fb1cd48f53 Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 27 Jun 2013 10:29:32 +0100 Subject: [PATCH] DMA-API: dma: pl330: add dma_set_mask_and_coherent() call 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 PL330 driver.
