Merge tag 'at91-fixes' of git://github.com/at91linux/linux-at91 into fixes
From Nicolas Ferre <nicolas.ferre@atmel.com>:
Two patches for Device Tree on at91sam9x5/NAND.
Two more for fixing PM suspend/resume IRQ on AIC5 and
GPIO used with pinctrl.
* tag 'at91-fixes' of git://github.com/at91linux/linux-at91:
ARM: at91: fix infinite loop in at91_irq_suspend/resume
ARM: at91: add gpio suspend/resume support when using pinctrl
ARM: at91: dt: at91sam9x5: complete NAND pinctrl
ARM: at91: dt: at91sam9x5: correct NAND pins comments
Includes an update to -rc2
