Changes are trivial under > arch/arm/ I looked at the series, it looks pretty good. Thanks for getting it done! No problem with entire series going through dmaengine. The week after next, when I am back in office, I would like to test on DM365 as well. But really no need to wait for it if the series is ready otherwise. Thanks, Sekhar
