Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for the v4.8 kernel cycle. Nothing stands out as especially exiting: new drivers, new subdrivers, lots of cleanups and incremental features. Business as usual. New drivers: - New driver for Oxnas pin control and GPIO. This ARM-based chipset is used in a few storage (NAS) type devices. - New driver for the MAX77620/MAX20024 pin controller portions. - New driver for the Intel Merrifield pin controller. New subdrivers: - New subdriver for the Qualcomm MDM9615 - New subdriver for the STM32F746 MCU - New subdriver for the Broadcom NSP SoC. Cleanups: - Demodularization of bool compiled-in drivers. Apart from this there is just regular incremental improvements to a lot of drivers, especially Uniphier and PFC" * tag 'pinctrl-v4.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (131 commits) pinctrl: fix pincontrol definition for marvell pinctrl: xway: fix typo Revert "pinctrl: amd: make it explicitly non-modular" pinctrl: iproc: Add NSP and Stingray GPIO support pinctrl: Update iProc GPIO DT bindings pinctrl: bcm: add OF dependencies pinctrl: ns2: remove redundant dev_err call in ns2_pinmux_probe() pinctrl: Add STM32F746 MCU support pinctrl: intel: Protect set wake flow by spin lock pinctrl: nsp: remove redundant dev_err call in nsp_pinmux_probe() pinctrl: uniphier: add Ethernet pin-mux settings sh-pfc: Use PTR_ERR_OR_ZERO() to simplify the code pinctrl: ns2: fix return value check in ns2_pinmux_probe() pinctrl: qcom: update DT bindings with ebi2 groups pinctrl: qcom: establish proper EBI2 pin groups pinctrl: imx21: Remove the MODULE_DEVICE_TABLE() macro Documentation: dt: Add new compatible to STM32 pinctrl driver bindings includes: dt-bindings: Add STM32F746 pinctrl DT bindings pinctrl: sunxi: fix nand0 function name for sun8i pinctrl: uniphier: remove pointless pin-mux settings for PH1-LD11 ...

+Broadcom NSP (Northstar plus) IOMUX Controller
+
+The NSP IOMUX controller supports group based mux configuration. In
+addition, certain pins can be muxed to GPIO function individually.
+
+Required properties:
+- compatible:
+ Must be "brcm,nsp-pinmux"
+
+- reg:
+ Should contain the register physical address and length for each of
+ GPIO_CONTROL0, GP_AUX_SEL and IPROC_CONFIG IOMUX registers
+
+Properties in subnodes:
+- function:
+ The mux function to select
+
+- groups:
+ The list of groups to select with a given function
+
+For more details, refer to
+Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
+
+For example:
+
+ pinmux: pinmux@1803f1c0 {
+ compatible = "brcm,nsp-pinmux";
+ reg = <0x1803f1c0 0x04>,
+ <0x18030028 0x04>,
+ <0x1803f408 0x04>;
+
+ pinctrl-names = "default";
+ pinctrl-0 = <&pwm &gpio_b &nand_sel>;
+
+ pwm: pwm {
+ function = "pwm";
+ groups = "pwm0_grp", "pwm1_grp";
+ };
+
+ gpio_b: gpio_b {
+ function = "gpio_b";
+ groups = "gpio_b_0_grp", "gpio_b_1_grp";
+ };
+
+ nand_sel: nand_sel {
+ function = "nand";
+ groups = "nand_grp";
+ };
+ };
