From 334ae614772b1147435dce9be3911f9040dff0d9 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 27 Aug 2008 17:01:57 -0700 Subject: sparc: Kill SBUS DVMA layer. This thing was completely pointless. Just find the OF device in the parent of drivers that want to program this device, and map the DMA regs inside such drivers too. This also moves the dummy claim_dma_lock() and release_dma_lock() implementation to floppy_32.h, which makes it handle this issue just like floppy_64.h does. Signed-off-by: David S.

Miller" Date: Wed, 27 Aug 2008 18:09:11 -0700 Subject: sparc: Convert all SBUS drivers to dma_*() interfaces. And all the SBUS dma interfaces are deleted. A private implementation remains inside of the 32-bit sparc port which exists only for the sake of the implementation of dma_*(). Signed-off-by: David S.
