Merge branch 'kirkwood/drivers' of git://git.infradead.org/users/jcooper/linux into late/kirkwood

From Jason Cooper:

New drivers:
 - pinctrl (dove, kirkwood, mvebu)
 - gpio (mvebu)

* 'kirkwood/drivers' of git://git.infradead.org/users/jcooper/linux:
  arm: mvebu: add gpio support in defconfig
  arm: mvebu: add DT information for GPIO banks on Armada 370 and XP
  arm: mvebu: use GPIO support now that a driver is available
  Documentation: add description of DT binding for the gpio-mvebu driver
  gpio: introduce gpio-mvebu driver for Marvell SoCs
  arm: mvebu: select the pinctrl drivers for Armada 370 and Armada XP platforms
  arm: mvebu: split Kconfig options for Armada 370 and XP
  ARM: mvebu: adjust Armada XP evaluation board DTS
  ARM: mvebu: Add pinctrl support to Armada 370 SoC
  ARM: mvebu: Add pinctrl support to Armada XP SoCs
  pinctrl: mvebu: add pinctrl driver for Armada XP
  pinctrl: mvebu: add pinctrl driver for Armada 370

+* Marvell EBU GPIO controller
+
+Required properties:
+
+- compatible : Should be "marvell,orion-gpio", "marvell,mv78200-gpio"
+  or "marvell,armadaxp-gpio". "marvell,orion-gpio" should be used for
+  Orion, Kirkwood, Dove, Discovery (except MV78200) and Armada
+  370. "marvell,mv78200-gpio" should be used for the Discovery
+  MV78200. "marvel,armadaxp-gpio" should be used for all Armada XP
+  SoCs (MV78230, MV78260, MV78460).
+
+- reg: Address and length of the register set for the device. Only one
+  entry is expected, except for the "marvell,armadaxp-gpio" variant
+  for which two entries are expected: one for the general registers,
+  one for the per-cpu registers.
+
+- interrupts: The list of interrupts that are used for all the pins
+  managed by this GPIO bank. There can be more than one interrupt
+  (example: 1 interrupt per 8 pins on Armada XP, which means 4
+  interrupts per bank of 32 GPIOs).
+
+- interrupt-controller: identifies the node as an interrupt controller
+
+- #interrupt-cells: specifies the number of cells needed to encode an
+  interrupt source. Should be two.
+  The first cell is the GPIO number.
+  The second cell is used to specify flags:
+    bits[3:0] trigger type and level flags:
+      1 = low-to-high edge triggered.
+      2 = high-to-low edge triggered.
+      4 = active high level-sensitive.
+      8 = active low level-sensitive.
+
+- gpio-controller: marks the device node as a gpio controller
+
+- ngpios: number of GPIOs this controller has
+
+- #gpio-cells: Should be two. The first cell is the pin number. The
+  second cell is reserved for flags, unused at the moment.
+
+Example:
+
+		gpio0: gpio@d0018100 {
+			compatible = "marvell,armadaxp-gpio";
+			reg = <0xd0018100 0x40>,
+			    <0xd0018800 0x30>;
+			ngpios = <32>;
+			gpio-controller;
+			#gpio-cells = <2>;
+			interrupt-controller;
+			#interrupt-cells = <2>;
+			interrupts = <16>, <17>, <18>, <19>;
+		};

Documentation/devicetree/bindings/pinctrl/marvell,mvebu-pinctrl.txt

+* Marvell SoC pinctrl core driver for mpp
+
+The pinctrl driver enables Marvell SoCs to configure the multi-purpose pins
+(mpp) to a specific function. For each SoC family there is a SoC specific
+driver using this core driver.
+
+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".
+
+A Marvell SoC pin configuration node is a node of a group of pins which can
+be used for a specific device or function. Each node requires one or more
+mpp pins or group of pins and a mpp function common to all pins.
+
+Required properties for pinctrl driver:
+- compatible: "marvell,<soc>-pinctrl"
+  Please refer to each marvell,<soc>-pinctrl.txt binding doc for supported SoCs.
+
+Required properties for pin configuration node:
+- marvell,pins: string array of mpp pins or group of pins to be muxed.
+- marvell,function: string representing a function to mux to for all
+    marvell,pins given in this pin configuration node. The function has to be
+    common for all marvell,pins. Please refer to marvell,<soc>-pinctrl.txt for
+    valid pin/pin group names and available function names for each SoC.
+

+

+ * struct mvebu_mpp_ctrl_setting - describe a mpp ctrl setting
+ * @val: ctrl setting value
+ * @name: ctrl setting name, e.g. uart2, spi0 - unique per mpp_mode
+ * @subname: (optional) additional ctrl setting name, e.g. rts, cts
+ * @variant: (optional) variant identifier mask
+ * @flags: (private) flags to store gpi/gpo/gpio capabilities
+ *
+ * A ctrl_setting describes a specific internal mux function that a mpp pin
+ * can be switched to. The value (val) will be written in the corresponding
+ * register for common mpp pin configuration registers on MVEBU. SoC specific
+ * mpp_get/_set function may use val to distinguish between different settings.
+ *
+ * The name will be used to switch to this setting in DT description, e.g.
+ * marvell,function = "uart2". subname is only for debugging purposes.
+ *
+ * If name is one of "gpi", "gpo", "gpio" gpio capabilities are
+ * parsed during initialization and stored in flags.
+ *
+ * The variant can be used to combine different revisions of one SoC to a
+ * common pinctrl driver. It is matched (AND) with variant of soc_info to
+ * determine if a setting is available on the current SoC revision.
