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.
