    Subject[PATCH 2/2] dt-bindings: pinctrl: mt8186: Add and use drive-strength-microamp
    Date
    Commit e5fabbe43f3f ("pinctrl: mediatek: paris: Support generic
    PIN_CONFIG_DRIVE_STRENGTH_UA") added support for using
    drive-strength-microamp instead of mediatek,drive-strength-adv.

    Similarly to the mt8192 and mt8195, there's no user of property
    'mediatek,drive-strength-adv', hence removing it is safe.

    Fixes: 338e953f1bd1(dt-bindings: pinctrl: mt8186: add pinctrl file and binding document)

    - 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)

    - 5: (E1, E0, EN) = (1, 0, 1)
    - 6: (E1, E0, EN) = (1, 1, 0)
    - 7: (E1, E0, EN) = (1, 1, 1)
    - So the valid arguments are from 0 to 7.
