Merge tag 'at91-dt' of git://github.com/at91linux/linux-at91 into next/dt

Merge "First batch of AT91 DT material for 3.15" from Nicolas Ferre:

- activate DMA for NAND flash controller
- some binding documentation update for usba and ADC (iio) drivers
- removal of some deprecated ADC (iio) properties
