Currently ufshcd driver assumes that bInitPowerMode parameter is not changed by any vendors thus device power mode can be set as "Active" during initialization. According to UFS JEDEC specification, device power mode shall be "Active" after HW Reset is triggered if the bInitPowerMode parameter in Device Descriptor is default value. By above description, we can set device power mode as "Active" after device reset is triggered by vendor's callback. With this change, the link startup performance can be improved in some cases by not setting link_startup_again as true in ufshcd_link_startup().

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.
