From 78060840cd2286c0e382641e60dcd4145f82f881 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Sat, 15 Feb 2014 04:26:52 +0300 Subject: [PATCH] ARM: shmobile: Armadillo 800 EVA: set proper DMA masks for Ether device Ether MAC is a DMA-capable device and so should have 'dev.dma_mask' and 'dev.coherent_dma_mask' fields set properly, to reflect 32-bit DMA addressing ability.
