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" * tag 'pinctrl-v3.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (61 commits) pinctrl: baytrail: Convert to use gpiolib irqchip pinctrl: sunxi: number gpio ranges starting from 0 pinctrl: sunxi: use gpiolib API to mark a GPIO used as an IRQ pinctrl: rockchip: add drive-strength control for rk3288 pinctrl: rockchip: add separate type for rk3288 pinctrl: rockchip: set is_generic in pinconf_ops pinctrl: msm: drop negativity check on unsigned value pinctrl: remove all usage of gpio_remove ret val in driver/pinctl pinctrl: qcom: Make muxing of gpio function explicit pinctrl: nomadik: move all Nomadik drivers to subdir pinctrl: samsung: Group all drivers in a sub-dir sh-pfc: sh73a0: Introduce the use of devm_regulator_register sh-pfc: Add renesas,pfc-r8a7791 to binding documentation pinctrl: msm: move all qualcomm drivers to subdir pinctrl: msm: Add msm8960 definitions pinctrl: samsung: Allow pin value to be initialized using pinfunc pinctrl: samsung: Allow grouping multiple pinmux/pinconf nodes pinctrl: exynos: Consolidate irq_chips of GPIO and WKUP EINTs pinctrl: samsung: Handle GPIO request and free using pinctrl helpers pinctrl: samsung: Decouple direction setting from pinctrl ...

+a general description of GPIO and interrupt bindings.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+The pin configuration nodes act as a container for an abitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+
+PIN CONFIGURATION NODES:
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+
+- pins:
+ Usage: required
+ Value type: <string-array>
