Merge tag 'at91-dt3' of git://github.com/at91linux/linux-at91 into next/dt
Pull "More AT91 DT material for 3.18" from Nicolas Ferre:
- specify DMA channels for USART on sama5d3 and choose peripherals
that will use them on the EK boards
- SSC update for audio on at91sam9rl and at91sam9g20
- addition of the NFC clock and new pinctrl compatible string
to use enhancements that will land in drivers during this release
- several new nodes and fixes
