Subject: [PATCH 04/24] ARM: move DMA alloc functions to dma.h
Date: Sun,  1 Mar 2015 14:17:02 +0100	[thread overview]
Message-ID: <1425215842-6982-5-git-send-email-dev@lynxeye.de> (raw)
In-Reply-To: <1425215842-6982-1-git-send-email-dev@lynxeye.de>

This better separates the DMA from the MMU functionality.

Also move all drivers that only depends on asm/mmu.h for the alloc
functions over to the common header.

Signed-off-by: Lucas Stach <dev@lynxeye.de>
