Merge tag 'at91-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/nferre/linux-at91 into next/dt
Merge "at91: dt for 3.20 #1" from Nicolas Ferre:
First batch of DT changes for 3.20:
- little typo and a LED declared
- addition of the Special Function Registers (SFR) + its binding
- RTC & SRAM nodes
- the at91sam9xe has its own .dtsi now. Not combined with at91sam9260 anymore
- addition of the Image Sensor Interface (ISI) DT part and supported sensors
