Merge tag 'at91-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/nferre/linux-at91 into next/soc
Merge "First little batch of SoC changes for 4.4" from Nicolas Ferre:
- a MAINTAINER addition to cover SAMA5 SoCs
- removal of one unneeded header file
- for low-level serial output, use the DEBUG_UART_PHYS
* tag 'at91-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/nferre/linux-at91:
ARM: at91: debug: use DEBUG_UART_PHYS
ARM: at91: remove useless includes in platform_data/atmel.h
MAINTAINERS: explicitly add Atmel SAMA5
