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
  pinctrl: mvebu: kirkwood pinctrl driver
  pinctrl: mvebu: dove pinctrl driver
  pinctrl: mvebu: pinctrl driver core

* 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>;

* 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.
Examples:
uart1: serial@12100 {
compatible = "ns16550a";
reg = <0x12100 0x100>;
reg-shift = <2>;
interrupts = <7>;
pinctrl-0 = <&pmx_uart1_sw>;
pinctrl-names = "default";
};
pinctrl: pinctrl@d0200 {
compatible = "marvell,dove-pinctrl";
reg = <0xd0200 0x20>;
pmx_uart1_sw: pmx-uart1-sw {
marvell,pins = "mpp_uart1";
marvell,function = "uart1";
};

*
* This driver is a fairly straightforward GPIO driver for the
* complete family of Marvell EBU SoC platforms (Orion, Dove,
* Kirkwood, Discovery, Armada 370/XP). The only complexity of this
* driver is the different register layout that exists between the
* non-SMP platforms (Orion, Dove, Kirkwood, Armada 370) and the SMP
* platforms (MV78200 from the Discovery family and the Armada
* XP). Therefore, this driver handles three variants of the GPIO
* block:
* - the basic variant, called "orion-gpio", with the simplest
* register set. Used on Orion, Dove, Kirkwoord, Armada 370 and
* non-SMP Discovery systems
* - the mv78200 variant for MV78200 Discovery systems. This variant
* turns the edge mask and level mask registers into CPU0 edge
* mask/level mask registers, and adds CPU1 edge mask/level mask
* registers.
* - the armadaxp variant for Armada XP systems. This variant keeps
* the normal cause/edge mask/level mask registers when the global
* interrupts are used, but adds per-CPU cause/edge mask/level mask
* registers n a separate memory area for the per-CPU GPIO
* interrupts.

* This file supports the three variants of Armada XP SoCs that are

* perspective, the mv78230 has 49 MPP pins. The mv78260 and mv78460
* both have 67 MPP pins (more GPIOs and address lines for the memory
* bus mainly). The only difference between the mv78260 and the
* mv78460 in terms of pin muxing is the addition of two functions on
* pins 43 and 56 to access the VDD of the CPU2 and 3 (mv78260 has two
* cores, mv78460 has four cores).
