From 1234e3fda9aa24b2d650bbcd9ef09d5f6a12dc86 Mon Sep 17 00:00:00 2001 From: Russell King Date: Fri, 24 Jul 2015 09:10:55 +0100 Subject: ARM: reduce visibility of dmac_* functions The dmac_* functions are private to the ARM DMA API implementation, and should not be used by drivers. In order to discourage their use, remove their prototypes and macros from asm/*.h. We have to leave dmac_flush_range() behind as Exynos and MSM IOMMU code use these; once these sites are fixed, this can be moved also.
