Merge tag 'at91-4.4-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux into fixes
Merge "Second fixes for 4.4" from Alexandre Belloni:
- fix of a hardware setup that prevents the sd/mmc interface to show up on
sama5d2.
- proper selection of pinctrl drivers. PIO4 is necessary for the sama5d2 to
boot.
* tag 'at91-4.4-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux:
ARM: at91: fix pinctrl driver selection
ARM: at91/dt: add always-on to 1.8V regulator
