Merge tag 'pinctrl-v5.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "It is pretty calm and chill in pin control for the moment. Just
  incremental development.

  There is an odd patch to the Super-H architecture, it's coming from
  the maintainers so should be fine.

  Summary:

  New drivers:
   - Bitmain BM1880 pin controller
   - Mediatek MT8516
   - Cirrus Logich Lochnagar PMIC pins

  Updates:
   - Incremental development on Renesas SH-PFC
   - Incremental development on Intel pin controller and some particular
     updates for Cedarfork.
   - Pin configuration support in Allwinner SunXi drivers
   - Suspend/resume support in the NXP/Freescale i.MX8MQ driver
   - Support for more packaging of the ST Micro STM32"

+Bitmain BM1880 Pin Controller
+
+This binding describes the pin controller found in the BM1880 SoC.
+
+Required Properties:
+
+- compatible:   Should be "bitmain,bm1880-pinctrl"
+- reg:          Offset and length of pinctrl space in SCTRL.
+
+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 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 for BM1880 SoC
+includes only pinmux as there is no pinconf support available in SoC.
+
+Each configuration node can consist of multiple nodes describing the pinmux
+options. The name of each subnode is not important; all subnodes should be
+enumerated and processed purely based on their content.
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pinmux subnode:
+
+Required Properties:
+
+- pins:           An array of strings, each string containing the name of a pin.

+Cirrus Logic Lochnagar Audio Development Board
+
+Lochnagar is an evaluation and development board for Cirrus Logic
+Smart CODEC and Amp devices. It allows the connection of most Cirrus
+Logic devices on mini-cards, as well as allowing connection of
+various application processor systems to provide a full evaluation
+platform.  Audio system topology, clocking and power can all be
+controlled through the Lochnagar, allowing the device under test
+to be used in a variety of possible use cases.
+
+This binding document describes the binding for the pinctrl portion
+of the driver.
+
+Also see these documents for generic binding information:
+  [1] GPIO : ../gpio/gpio.txt
+  [2] Pinctrl: ../pinctrl/pinctrl-bindings.txt
+
+And these for relevant defines:
+  [3] include/dt-bindings/pinctrl/lochnagar.h
+
+This binding must be part of the Lochnagar MFD binding:
+  [4] ../mfd/cirrus,lochnagar.txt
+
+Required properties:
+
+  - compatible : One of the following strings:
+                 "cirrus,lochnagar-pinctrl"
+
+  - gpio-controller : Indicates this device is a GPIO controller.
+  - #gpio-cells : Must be 2. The first cell is the pin number, see
+    [3] for available pins and the second cell is used to specify
+    optional parameters, see [1].
+  - gpio-ranges : Range of pins managed by the GPIO controller, see
+    [1]. Both the GPIO and Pinctrl base should be set to zero and the
+    count to the appropriate of the LOCHNAGARx_PIN_NUM_GPIOS define,
+    see [3].
+
+  - pinctrl-names : A pinctrl state named "default" must be defined.
+  - pinctrl-0 : A phandle to the default pinctrl state.
+
+Required sub-nodes:
+
+The pin configurations are defined as a child of the pinctrl states
+node, see [2]. Each sub-node can have the following properties:

+* Mediatek MT8183 Pin Controller
+
+The Mediatek's Pin controller is used to control SoC pins.
+
+Required properties:
+- compatible: value should be one of the following.
+	"mediatek,mt8183-pinctrl", compatible with mt8183 pinctrl.
+- 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.
+- gpio-ranges : gpio valid number range.
+- reg: physical address base for gpio base registers. There are 10 GPIO
+  physical address base in mt8183.
+
+Optional properties:
+- reg-names: gpio base register names. There are 10 gpio base register
+  names in mt8183. They are "iocfg0", "iocfg1", "iocfg2", "iocfg3", "iocfg4",
+  "iocfg5", "iocfg6", "iocfg7", "iocfg8", "eint".
+- interrupt-controller: Marks the device node as an interrupt controller
+- #interrupt-cells: Should be two.
+- interrupts : The interrupt outputs to sysirq.
+
+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 It needs config "mediatek,pull-up-adv" or
+    "mediatek,pull-down-adv" to support arguments for those special pins.
+    Valid arguments are from 0 to 3.
+
+    mediatek,tdsel: An integer describing the steps for output level shifter
+      duty cycle when asserted (high pulse width adjustment). Valid arguments
+      are from 0 to 15.
+    mediatek,rdsel: An integer describing the steps for input level shifter
+      duty cycle when asserted (high pulse width adjustment). Valid arguments
+      are from 0 to 63.
+
+    When config drive-strength, it can support some arguments, such as
+    MTK_DRIVE_4mA, MTK_DRIVE_6mA, etc. See dt-bindings/pinctrl/mt65xx.h.
+    It can only support 2/4/6/8/10/12/14/16mA in mt8183.
+    For I2C pins, there are existing generic driving setup and the specific
+    driving setup. I2C pins can only support 2/4/6/8/10/12/14/16mA driving
+    adjustment in generic driving setup. But in specific driving setup,
+    they can support 0.125/0.25/0.5/1mA adjustment. If we enable specific
+    driving setup for I2C pins, the existing generic driving setup will be
+    disabled. For some special features, we need the I2C pins specific
+    driving setup. The specific driving setup is controlled by E1E0EN.
+    So we need add extra vendor driving preperty instead of
+    the generic driving property.
+    We can add "mediatek,drive-strength-adv = <XXX>;" to describe the specific
+    driving setup property. "XXX" means the value of E1E0EN. EN is 0 or 1.
+    It is used to enable or disable the specific driving setup.
+    E1E0 is used to describe the detail strength specification of the I2C pin.
+    When E1=0/E0=0, the strength is 0.125mA.
+    When E1=0/E0=1, the strength is 0.25mA.
+    When E1=1/E0=0, the strength is 0.5mA.
+    When E1=1/E0=1, the strength is 1mA.
+    So the valid arguments of "mediatek,drive-strength-adv" are from 0 to 7.
