Hi All,
I'm just looking into implementing the Freescale i.MX SDMA engine in the dmaengine API. One usecase of this dma engine is sound. After some digging I found the following commit:
commit d9de451989a88a2003ca06e524aca4665c0c7f06 Author: Hans-Christian Egtvedt <hans-christian.egtvedt@atmel.com> Date: Wed Apr 1 15:47:02 2009 +0200
dw_dmac: add cyclic API to DW DMA driver
This could be very useful for the SDMA engine aswell. What are the reasons this is not implemented in the generic dmaengine API but as an extension to a specific driver? Should I also implement it like this or isn't it better to extend the dmaengine itself?
Sascha
