So far, all DMA channels are described using auxdata on platforms that use DT, with the exception of exynos, but that one will have to change once we have the common code.

You're talking about the DT bindings here, right? But the code itself is also only present in TI's BSP kernel sources, and not in mainline.

Matt Porter from TI is working on moving this to DMA engine. Once that's done the driver should be usable on AM335x too. Have a look at the wiki page Vaibhav posted under the thread "Current state of AM33xx patches" Thanks, Sekhar ^ permalink raw reply [flat|nested] 10+ messages in thread

This would still be some time away since there is a bunch of work involved here. To make progress on Audio DT conversion Gururaja is doing an up port of AM335x EDMA support from TI release to mainline kernel. If you are interested in it, he can probably share that with you once he posts his DT patches. Thanks, Sekhar ^ permalink raw reply [flat|nested] 10+ messages in thread

As the DMA engine is also a requirement for the MMC controller, I would be interested in helping, in case help is required. Is there any repository with code that I can have a look at?

Is there any > repository with code that I can have a look at? I'm just getting to the point now where I *almost* have something to push to my github repo and post. It'll be Davinci-specific to start since it's a wrapper around mach-davinci/dma.c and includes only memcpy and SG transfer type support initially...plus conversions of davinci spi/mmc drivers. There'll be a bit of work to get the omap-dma.c-dependent channel filtering removed from the omap hsmmc and mcspi drivers so they can provide a filter that works with either dmaengine driver. Also, that means DT support for the actual dmaengine driver too and some glue to configure the crossbar. I'll copy you when I get this RFC series posted and we can go from there. -Matt ^ permalink raw reply [flat|nested] 10+ messages in thread
