+ Describe the specific driving setup property.
+ For I2C pins, the existing generic driving setup can only support
+ 2/4/6/8/10/12/14/16mA driving. But in specific driving setup, they
+ can support 0.125/0.25/0.5/1mA adjustment. If we enable specific
+ 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)
+ 2: (E1, E0, EN) = (0, 1, 0)

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

-
-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.

- 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.

-
-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.

- 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.

+++ /dev/null
-* 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.
