[PATCH 0/4] ARM: davinci: Remove DMA resources for MMC/SPI

[Peter Ujfalusi]

Hi,

The drivers for davinci MMC and SPI have been converted to the new DMAengine API
and no longer rely on the IORESOURCE_DMA.
This is the case for at least one release cycle so now we can remove the
IORESOURCE_DMA for these devices.

Regards,
Peter

Hi Peter, applied to v4.10/cleanup branch of my tree. Thanks!
