Yeah, are you ok with a follow on series to clean all these files? I don't want to make this series longer with something not dma related that's purely cleanup from the great header reorg of 2012. > > + > > > > #include "davinci.h" > > #include "clock.h" > > @@ -141,10 +142,10 @@ static struct resource mmcsd0_resources[] = { > > }, > > /* DMA channels: RX, then TX */ > > { > > - .start = EDMA_CTLR_CHAN(0, DAVINCI_DMA_MMCRXEVT), > > + .start = EDMA_CTLR_CHAN(0, 26), > > Instead of just replacing the event #defines with plain numbers, can you > introduce a mach-davinci local edma.h which can then be included in the > davinci platform files which refer to edma channel numbers? Ok, so when I removed the old edma.h it was full of unused defines and we are left with just this one. If I introduced something like that it would be used in just one place here. and only for these two values. How about we just add a comment? > > > diff --git a/arch/arm/plat-omap/Kconfig b/arch/arm/plat-omap/Kconfig > > index 7cd56ed..153fab8 100644 > > --- a/arch/arm/plat-omap/Kconfig > > +++ b/arch/arm/plat-omap/Kconfig > > @@ -28,6 +28,7 @@ config ARCH_OMAP2PLUS > > select OMAP_DM_TIMER > > select PROC_DEVICETREE if PROC_FS > > select SPARSE_IRQ > > + select TI_PRIV_EDMA > > This hunk does not seem to belong to subject of this patch. Let me reword the subject/description. The idea of this logical chunk was to put everything in place to make it build on OMAP, with the expectation that the build fails without the next patch in the series. > > select USE_OF > > help > > "Systems based on OMAP2, OMAP3, OMAP4 or OMAP5" > > > diff --git a/include/linux/platform_data/edma.h b/include/linux/platform_data/edma.h > > new file mode 100644 > > index 0000000..7396f0b3 > > --- /dev/null > > +++ b/include/linux/platform_data/edma.h > > @@ -0,0 +1,198 @@ > > +/* > > + * TI DAVINCI dma definitions > > + * > > + * Copyright (C) 2006-2009 Texas Instruments. > > + * > > + * This program is free software; you can redistribute it and/or modify it > > + * under the terms of the GNU General Public License as published by the > > + * Free Software Foundation; either version 2 of the License, or (at your > > + * option) any later version. > > + * > > + * THIS SOFTWARE IS PROVIDED ``AS IS'' AND ANY EXPRESS OR IMPLIED > > + * WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF > > + * MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE DISCLAIMED.

Matt, Sorry about the late reply.

But this will break bisect. With just this patch applied, omap build breaks. Looks like it will be more logical to merge this hunk with 3/14 since that's when you really start using the private DMA support on OMAP platforms. This issue is a must fix IMO. I am ok with the patch otherwise.
