+Subject: [PATCH 1/2] arm: ixp4xx: set cohorent_dma_mask for ethernet platform
+ devices
+
+ARM requires the cohorent_dma_mask set, so set it for the platform
+devices so that the ethernet driver has access to it.

+Subject: [PATCH 2/2] net: ixp4xx_eth: use parent device for dma allocations
+
+Now that the platfomr device provides a dma_cohorent_mask, use it for
+dma operations.
+
+This fixes ethernet on ixp4xx which was broken since 3.7.
