There are couple of users currently that have a private DMA IP attached to the
main device, namely ADSP and serial. They would like to do a DMA for
operations. Thus, we share dw_dma_probe() and dw_dma_remove().
The DMA controller is enabled automatically whenever first user aquires a
channel, and disabled when the last one release a channel.
Patchseries was tested on Bay Trail with ADSP hardware by Liam (Cc'ed).
Andy Shevchenko (6):
dmaengine: dw: move private definitions to regs.h
dmaengine: dw: split dma-dw.h to platform and private parts
dmaengine: dw: introduce dw_dma_on() helper
dmaengine: dw: always export dw_dma_{en,dis}able
dmaengine: dw: enable and disable controller when needed
dmaengine: dw: export probe()/remove() and Co to users
