Light Hsieh 3d7b213d92 pinctrl: mediatek: Supporting driving setting without mapping current to register value
[ Upstream commit 5f755e1f1efe5ca3b475b14169e6e85bf1411bb5 ]

MediaTek's smartphone project actual usage does need to know current value
(in mA) in procedure of finding the best driving setting.
The steps in the procedure is like as follow:

1. set driving setting field in setting register as 0, measure waveform,
   perform test, and etc.
2. set driving setting field in setting register as 1, measure waveform,
   perform test, and etc.
...
n. set driving setting field in setting register as n-1, measure
   waveform, perform test, and etc.
Check the results of steps 1~n and adopt the setting that get best result.

This procedure does need to know the mapping between current to register
value.
Therefore, setting driving without mapping current is more practical for
MediaTek's smartphone usage.

README

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.
