Merge tag 'pinctrl-v3.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pinctrl updates from Linus Walleij:
 "This is the bulk pin control changes for the v3.17 merge development
  cycle:

   - get rid of the .disable() callback from the driver callback vtable.

     This callback was abused and counterintuitive since a pin or group
     of pins can be said to always be in some setting, and never really
     disabled.  We now only enable a certain muxing, and move between
     some certain muxings, we never "disable" a mux setting

   - some janitorial moving the MSM, Samsung and Nomadik and drivers to
     their own subdirectories for a clearer view in the subsystem.  This
     will continue

   - kill off the use of the return value from gpiochip_remove(), this
     will be done in parallel in the GPIO subsystem and hopefully not
     trigger too many unchecked return value warnings before we get rid
     of this altogether

   - a huge set of changes and improvements to the Allwinner sunxi
     drivers especially for their latest A23 and A31 SoCs, and some
     ground work for the new sun8i platform family

   - a large set of Rockchip driver improvements adding support for the
     RK3288 SoC

   - advances in migration of older Freescale platforms to pin control,
     especially i.MX1

   - Samsung and Exynos improvements

   - support for the Qualcomm MSM8960 SoC

   - use the gpiolib irqchip helpers for the ST SPEAr and Intel Baytrail
     drivers

   - a bunch of nice janitorial work done with cppcheck"
