+              driving setup, the existing generic setup will be disabled.
+              The specific driving setup is controlled by E1E0EN.
+              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.
+              EN is used to enable or disable the specific driving setup.
+              Valid arguments are described as below:
+              0: (E1, E0, EN) = (0, 0, 0)
+              1: (E1, E0, EN) = (0, 0, 1)

-- 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
-
-Optional properties:
-- mediatek,pctl-regmap: Should be a phandle of the syscfg node.

-
-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.

-== MediaTek MT7622 pinctrl controller ==
-
-Required properties for the root node:
- - compatible: Should be one of the following
-	       "mediatek,mt7622-pinctrl" for MT7622 SoC
-	       "mediatek,mt7629-pinctrl" for MT7629 SoC
- - reg: offset and length of the pinctrl space
-
- - gpio-controller: Marks the device node as a GPIO controller.
- - #gpio-cells: Should be two. The first cell is the pin number and the
-   second is the GPIO flags.
-
-Optional properties:
-- interrupt-controller  : Marks the device node as an interrupt controller
-
-If the property interrupt-controller is defined, following property is required
-- reg-names: A string describing the "reg" entries. Must contain "eint".
-- interrupts : The interrupt output from the controller.
-- #interrupt-cells: Should be two.
-
-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".
-
-MT7622 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, slew rate, etc.
-
-We support 2 types of configuration nodes. Those nodes can be either pinmux
-nodes or pinconf nodes. Each configuration node can consist of multiple nodes
-describing the pinmux and pinconf options.
-
-The name of each subnode doesn't matter as long as it is unique; all subnodes
-should be enumerated and processed purely based on their content.
-
-== pinmux nodes content ==
-
-The following generic properties as defined in pinctrl-bindings.txt are valid
-to specify in a pinmux subnode:
-
-Required properties are:
- - groups: An array of strings. Each string contains the name of a group.
-  Valid values for these names are listed below.
- - function: A string containing the name of the function to mux to the
-  group. Valid values for function names are listed below.
-
-== pinconf nodes content ==
-
-The following generic properties as defined in pinctrl-bindings.txt are valid
-to specify in a pinconf subnode:
-
-Required properties are:
- - pins: An array of strings. Each string contains the name of a pin.
-  Valid values for these names are listed below.
- - groups: An array of strings. Each string contains the name of a group.
-  Valid values for these names are listed below.
-
-Optional properies are:
- bias-disable, bias-pull, bias-pull-down, input-enable,
- input-schmitt-enable, input-schmitt-disable, output-enable
- output-low, output-high, drive-strength, slew-rate
-
- Valid arguments for 'slew-rate' are '0' for no slew rate controlled and '1' for
- slower slew rate respectively.
- Valid arguments for 'drive-strength', 4, 8, 12, or 16 in mA.
-
-The following specific properties as defined are valid to specify in a pinconf
-subnode:
-
-Optional properties are:
- - 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.
-
-== Valid values for pins, function and groups on MT7622 ==
-
-Valid values for pins are:
-pins can be referenced via the pin names as the below table shown and the
-related physical number is also put ahead of those names which helps cross
-references to pins between groups to know whether pins assignment conflict
-happens among devices try to acquire those available pins.

-* 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.
