Merge tag 'pinctrl-v4.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pincontrol updates from Linus Walleij:
 "This is the bulk of pin control changes for the v4.1 development
  cycle.  Nothing really exciting this time: we basically added a few
  new drivers and subdrivers and stabilized them in linux-next.  Some
  cleanups too.  With sunrisepoint Intel has a real fine fully featured
  pin control driver for contemporary hardware, and the AMD driver is
  also for large deployments.  Most of the others are ARM devices.

  New drivers:
    - Intel Sunrisepoint
    - AMD KERNCZ GPIO
    - Broadcom Cygnus IOMUX

  New subdrivers:
    - Marvell MVEBU Armada 39x SoCs

NVIDIA Tegra210 pinmux controller
Required properties:
- compatible: "nvidia,tegra210-pinmux"
- reg: Should contain a list of base address and size pairs for:
- first entry: The APB_MISC_GP_*_PADCTRL registers (pad control)
- second entry: The PINMUX_AUX_* registers (pinmux)
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".
Tegra's pin configuration nodes act as a container for an arbitrary 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, tristate, drive strength, etc.
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 or tristate parameter. For this
reason, even seemingly boolean values are actually tristates in this binding:
unspecified, off, or on. Unspecified is represented as an absent property,
and off/on are represented as integer values 0 and 1.
See the TRM to determine which properties and values apply to each pin/group.
Macro values for property values are defined in
include/dt-binding/pinctrl/pinctrl-tegra.h.
Required subnode-properties:
- nvidia,pins : An array of strings. Each string contains the name of a pin or
group. Valid values for these names are listed below.
Optional subnode-properties:
- nvidia,function: A string containing the name of the function to mux to the
pin or group.
- nvidia,pull: Integer, representing the pull-down/up to apply to the pin.
0: none, 1: down, 2: up.
- nvidia,tristate: Integer.
0: drive, 1: tristate.
- nvidia,enable-input: Integer. Enable the pin's input path.
enable :TEGRA_PIN_ENABLE0 and
disable or output only: TEGRA_PIN_DISABLE.
- nvidia,open-drain: Integer.
enable: TEGRA_PIN_ENABLE.
disable: TEGRA_PIN_DISABLE.
- nvidia,lock: Integer. Lock the pin configuration against further changes
until reset.
enable: TEGRA_PIN_ENABLE.
disable: TEGRA_PIN_DISABLE.
- nvidia,io-hv: Integer. Select high-voltage receivers.
normal: TEGRA_PIN_DISABLE
high: TEGRA_PIN_ENABLE
- nvidia,high-speed-mode: Integer. Enable high speed mode the pins.
normal: TEGRA_PIN_DISABLE
high: TEGRA_PIN_ENABLE
- nvidia,schmitt: Integer. Enables Schmitt Trigger on the input.
normal: TEGRA_PIN_DISABLE
high: TEGRA_PIN_ENABLE
- nvidia,drive-type: Integer. Valid range 0...3.
- nvidia,pull-down-strength: Integer. Controls drive strength. 0 is weakest.
The range of valid values depends on the pingroup. See "CAL_DRVDN" in the
Tegra TRM.
- nvidia,pull-up-strength: Integer. Controls drive strength. 0 is weakest.
The range of valid values depends on the pingroup. See "CAL_DRVUP" in the
Tegra TRM.
- nvidia,slew-rate-rising: Integer. Controls rising signal slew rate. 0 is
fastest. The range of valid values depends on the pingroup. See
"DRVDN_SLWR" in the Tegra TRM.
- nvidia,slew-rate-falling: Integer. Controls falling signal slew rate. 0 is
fastest. The range of valid values depends on the pingroup. See
"DRVUP_SLWF" in the Tegra TRM.
Valid values for pin and group names (nvidia,pin) are:
Mux groups:
These correspond to Tegra PINMUX_AUX_* (pinmux) registers. Any property
that exists in those registers may be set for the following pin names.
In Tegra210, many pins also have a dedicated APB_MISC_GP_*_PADCTRL
register. Where that is true, and property that exists in that register
may also be set on the following pin names.

* Mediatek MT65XX Pin Controller
The Mediatek's Pin controller is used to control SoC pins.
Required properties:
- compatible: value should be either of the following.
(a) "mediatek,mt8135-pinctrl", compatible with mt8135 pinctrl.
- mediatek,pctl-regmap: Should be a phandle of the syscfg node.
- pins-are-numbered: Specify the subnodes are using numbered pinmux to
specify pins.
- gpio-controller : Marks the device node as a gpio controller.
- #gpio-cells: number of cells in GPIO specifier. Since the generic GPIO
binding is used, the amount of cells must be specified as 2. See the below
mentioned gpio binding representation for description of particular cells.
Eg: <&pio 6 0>
<[phandle of the gpio controller node]
[line number within the gpio controller]
[flags]>
Values for gpio specifier:
- Line number: is a value between 0 to 202.
- Flags: bit field of flags, as defined in <dt-bindings/gpio/gpio.h>.
Only the following flags are supported:
0 - GPIO_ACTIVE_HIGH
1 - GPIO_ACTIVE_LOW
- reg: physicall address base for EINT registers
- interrupt-controller: Marks the device node as an interrupt controller
- #interrupt-cells: Should be two.
- interrupts : The interrupt outputs from the controller.
Please refer to pinctrl-bindings.txt in this directory for details of the
common pinctrl bindings used by client devices.
Subnode format
A pinctrl node should contain at least one subnodes representing the
pinctrl groups available on the machine. Each subnode will list the
pins it needs, and how they should be configured, with regard to muxer
configuration, pullups, drive strength, input enable/disable and input schmitt.
node {
pinmux = <PIN_NUMBER_PINMUX>;
GENERIC_PINCONFIG;
};
Required properties:
- pinmux: integer array, represents gpio pin number and mux setting.
Supported pin number and mux varies for different SoCs, and are defined
as macros in boot/dts/<soc>-pinfunc.h directly.
Optional properties:
- GENERIC_PINCONFIG: is the generic pinconfig options to use, bias-disable,
bias-pull-down, bias-pull-up, input-enable, input-disable, output-low, output-high,
input-schmitt-enable, input-schmitt-disable and drive-strength are valid.
Some special pins have extra pull up strength, there are R0 and R1 pull-up
resistors available, but for user, it's only need to set R1R0 as 00, 01, 10 or 11.
So when config bias-pull-up, it support arguments for those special pins.
Some macros have been defined for this usage, such as MTK_PUPD_SET_R1R0_00.
See dt-bindings/pinctrl/mt65xx.h.
When config drive-strength, it can support some arguments, such as
MTK_DRIVE_4mA, MTK_DRIVE_6mA, etc. See dt-bindings/pinctrl/mt65xx.h.
