From 4bab9d426e6dbd9ea09330919a33d35d5faab400 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Fri, 19 Mar 2010 04:46:38 +0000 Subject: dmaengine: shdma: Remove sh_dmae_slave_chan_id enum This patch replaces the sh_dmae_slave_chan_id enum with an unsigned int. The purpose of this chainge is to make it possible to separate the slave id enums from the dmaengine header. The slave id enums varies with processor model, so in the future it makes sense to put these in the processor specific headers together with the pinmux enums.

This is done by moving common structures from sh asm/dmaengine.h to linux/sh_dma.h. DMA registers are also copied from sh asm/dma-register.h to make the code architecture independent. The sh header file asm/dmaengine.h is still kept with the slave id enum. This allows us to keep the old processor specific code as is and slowly move over to slave id enums in per-processor headers.
