X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5c65c360da06635f985684fa0ab41027660d0804;p=linux-beck.git

ARM: OMAP: add deprecation message for legacy OMAP DMA API

The legacy OMAP DMA API is now deprecated; all remaining users should
now convert over ASAP to using the DMA engine API instead of the OMAP
private API.
