    Subject[PATCH v2 0/4] Add drive-strength in Meson pinctrl driver
    Date
    The purpose of this patchset is to add drive-strength support in meson pinconf
    driver. This is a new feature that was added on the g12a. It is critical for us
    to support this since many functions are failing with default pad drive-strength.

    The value achievable by the SoC are 0.5mA, 2.5mA, 3mA and 4mA and the DT property
    'drive-strength' is expressed in mA.
    So this patch add another generic property "drive-strength-uA". The change to do so
    would be minimal and could be benefit to other platforms later on.

    Cheers
    Guillaume

    Changes since v1:
    - fix missing break
    - implement new pinctrl generic property "drive-strength-uA"
