Merge tag 'pinctrl-v4.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"This kernel cycle was quite calm when it comes to pin control and
there is really just one major change, and that is the introduction of
devm_pinctrl_register() managed resources.
Apart from that linear development, details below.
Core changes:
- Add the devm_pinctrl_register() API and switch all applicable
drivers to use it, saving lots of lines of code all over the place.
New drivers:
- driver for the Broadcom NS2 SoC
- subdriver for the PXA25x SoCs
- subdriver for the AMLogic Meson GXBB SoC
Driver improvements:
- the Intel Baytrail driver now properly supports pin control
- Nomadik, Rockchip, Broadcom BCM2835 support the .get_direction()
callback in the GPIO portions
- continued development and stabilization of several SH-PFC SoC
subdrivers: r8a7795, r8a7790, r8a7794 etc"
