On certain SoCs, power regulators are shared between the QMP UFS PHY and other IP blocks. To ensure proper operation, the regulator framework must be informed of the UFS PHY's load requirements. This is essential because the regulator's operating mode—whether Low Power or High Power—depends on the maximum expected load at any given time, which the regulator driver needs to manage accordingly. To support this, replace devm_regulator_bulk_get() with devm_regulator_bulk_get_const() and inline the qmp_ufs_vreg_init() function. additionally replace the array of regulator names with a bulk regulator data structure, and utilize the init_load_uA field provided by the regulator framework. This ensures that regulator_set_load() is automatically invoked before the first enable operation.

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 reStructuredText 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.
