Felipe, This code is also being used for other architectures such as OMAP3517, OMAPL13x etc. Given this I do not think we can locate it under a mach-* directory. Have corrected the wrap issue. Thanks for point it out. regards swami ________________________________________ From: Felipe Balbi [me@xxxxxxxxxxxxxxx] Sent: Wednesday, December 30, 2009 5:54 PM To: Subbrathnam, Swaminathan Cc: felipe.balbi@xxxxxxxxx; Gupta, Ajay Kumar; linux-usb@xxxxxxxxxxxxxxx; linux-arm-kernel@xxxxxxxxxxxxxxxxxxx; Sergei Shtylyov Subject: Re: [PATCH RFC 1/2] MUSB: CPPI 4.1 DMA driver (take 4) Hi, please wrap your mails at 80 characters On Wed, Dec 30, 2009 at 09:16:08AM +0530, Subbrathnam, Swaminathan wrote: > We have been on this front months together now!!!

Appreciate everybody's feedback and > direction. You can do like omap and have the generic dma interface sitting in mach-davinci, then for musb, you'd have a series of wrappers to use the cppi dma code. Just look at arch/arm/plat-omap/dma.c and drivers/usb/musb/tusb6010_omap.c -- balbi-- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
