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)

6: (E1, E0, EN) = (1, 1, 0)
7: (E1, E0, EN) = (1, 1, 1)

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

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.
