I am wondering if any progress has been made in getting Device Tree Overlays (via uBoot) to correctly allow DMA to be used on the SPI devices. I have not seen any *recent* mention of this issue. Referring to these previous articles:
https://groups.google.com/forum/?fromgroups#!searchin/beagleboard/spi$20dma%7Csort:date/beagleboard/YV5qDHTgtBQ/MAI1s-PUAQAJ and https://groups.google.com/forum/?fromgroups#!searchin/beagleboard/spi$20dma%7Csort:date/beagleboard/_22bW7vMkW0/rn01nfvyBQAJ It is suggested that should you want to use DMA with SPI, enable the SPI in the main DTB (*sigh*). Is this still the case? If so, does it even make sense to use DT Overlays for any other resources I am using (GPIO's for example)? Since I'm hacking up the main DTB anyway, why not just add everything I need there and not worry about the uBoot DT Overlays at all? Thanks so much for any insight anyone may have into this.
