Merge tag 'at91-dt' of git://github.com/at91linux/linux-at91 into next/dt
From Nicolas Ferre: Again some nice DT updates for AT91: - DMA binding update with one patch shared with slave-dma tree - more SPI DT activation - enable the USB gadget HS for DT platforms * tag 'at91-dt' of git://github.com/at91linux/linux-at91: ARM: at91: sam9m10g45ek add udc DT support ARM: at91: sam9g45 add udc DT support ARM: at91: sam9x5ek add udc DT support ARM: at91: sam9x5 add udc DT support ARM: at91: dt: at91sam9x5: add SPI DMA client infos ARM: at91: dt: switch DMA DT bindings to pre-processor ARM: at91: dt: add header to define at_hdmac configuration
