Add support for DLVR (Digital Linear Voltage Regulator) attributes, which can be used to control RFIM. Here instead of "fivr" another directory "dlvr" is created with DLVR attributes: /sys/bus/pci/devices/0000:00:04.0/dlvr ├── dlvr_freq_mhz ├── dlvr_freq_select ├── dlvr_hardware_rev ├── dlvr_pll_busy ├── dlvr_rfim_enable └── dlvr_spread_spectrum_pct └── dlvr_control_mode └── dlvr_control_lock Attributes dlvr_freq_mhz (RO): Current DLVR PLL frequency in MHz. dlvr_freq_select (RW): Sets DLVR PLL clock frequency. dlvr_hardware_rev (RO): DLVR hardware revision. dlvr_pll_busy (RO): PLL can't accept frequency change when set. dlvr_rfim_enable (RW): 0: Disable RF frequency hopping, 1: Enable RF frequency hopping. dlvr_control_mode (RW): Specifies how frequencies are spread. 0: Down spread, 1: Spread in Center. dlvr_control_lock (RW): 1: future writes are ignored. dlvr_spread_spectrum_pct (RW) A write to this register updates the DLVR spread spectrum percent value.

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.
