From 1e6eebb4e907548d53347a6e90769feb3d73e9da Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Wed, 15 May 2013 10:51:45 +0100 Subject: [PATCH] usb: musb: ux500: take the dma_mask from coherent_dma_mask The dma_mask will always be the same as the coherent_dma_mask, so let's cut down on the platform_data burden and set it as such in the driver. This also saves us from supporting it separately when we come to enable this driver for Device Tree.
