[PATCH 3/8] ARM: OMAP2+: hwmod: Remove remaining DMA channel definitions

Jarkko Nikula jarkko.nikula at bitmer.com
Sat Jun 15 04:31:04 EDT 2013 

Last remaining DMA channel definitions in arch/arm/mach-omap2/dma.h
are used only by omap_hwmod_2xxx_3xxx_ipblock_data.c and
omap_hwmod_3xxx_data.c. Remove them by using directly DMA channel number in
hwmod data and drop definitions with a following script:

egrep '#define [OMAP|AM35XX].*DMA' arch/arm/mach-omap2/dma.h | cut -f 1,3 \
	| while read i; do \
		DEF=`echo $i |cut -d ' ' -f 2`; \
		CH=`echo $i |cut -d ' ' -f 3`; \
		echo "removing" $DEF; \
		sed -i "s/${DEF}/${CH}/" arch/arm/mach-omap2/omap_hwmod_*.c; \
		sed -i "/${DEF}/d" arch/arm/mach-omap2/dma.h; \
	done
