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

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

- some updates on the defconfig front
- two SoCs converted to Device Tree: sam9261 and sam9rl
  (with use of CCF!)
- a little PWM clock update that goes on top of this
