Some of the MediaTek chips that utilize the Paris pinctrl driver library support a lower drive strength (<= 1mA) than the standard drive strength settings (2~16 mA) on certain pins. This was previously supported by the custom MTK_PIN_CONFIG_DRV_ADV parameter along with the "mediatek,drive-strength-adv" device tree property. The drive strength values for this hardware are 125, 250, 500, and 1000 mA, and can be readily described by the existing "drive-strength-microamp" property, which then gets parsed by the generic pinconf library into the parameter PIN_CONFIG_DRIVE_STRENGTH_UA. Add support for PIN_CONFIG_DRIVE_STRENGTH_UA while keeping the old custom parameter around for backward compatibility.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
