Currently if a regulator has "<name>-fixed-regulator" property in device tree, it will skip current limit initialization. This lead to a zero "max_uA" value in struct ufs_vreg. However, "regulator_set_load" operation shall be required on regulators which have valid current limits, otherwise a zero "max_uA" set by "regulator_set_load" may cause unexpected behavior when this regulator is enabled or set as high power mode. Similarly, in device's icc_level configuration flow, the target icc_level shall be updated if regulator also has valid current limit, otherwise a wrong icc_level will be calculated by zero "max_uA" and thus causes unexpected results after it is written to device.

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.
