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

From Nicolas Ferre:
First series of AT91 fixes for 3.14.
All of them are DT-related.
- fixes for typos in i2c and ohci clocks
- addition of a USB host node for at91sam9n12ek
- 2 DT documentation updates that have been sent a long time ago
- a new board based on the sama5d36 SoC

* tag 'at91-fixes' of git://github.com/at91linux/linux-at91

:
  ARM: at91: add Atmel's SAMA5D3 Xplained board
  spi/atmel: document clock properties
  mmc: atmel-mci: document clock properties
  ARM: at91: enable USB host on at91sam9n12ek board
  ARM: at91/dt: fix sama5d3 ohci hclk clock reference
  ARM: at91/dt: sam9263: fix compatibility string for the I2C
