Subject: [PATCH] OF: update coherent_dma_mask
Date: Mon, 10 Dec 2012 17:39:29 +0530 [thread overview]
Message-ID: <1355141369-30030-1-git-send-email-subash.rp@samsung.com> (raw)
This patch is tested in ARM:exynos5250 with LPAE enabled. The coherent_dma_mask
needs to be defined to DMA_BIT_MASK(64) as dma-mapping API's check it against
64-bit mask.
