 This parameter is meaningful only when the "desired" field above is non-zero.
 Default is 0, allowing the HW to choose.

+Note that the Platform Profile Name must be "SoC Slider", and the
+Platform Profile must be "balanced" for the --soc-slider-balance

+\fB--soc-slider-balance #\fP write numeric value to the SoC Slider.
+Values range from 0 to 6.
+Lower values result in higher performance,
+and higher values improve energy efficiency.
+Actual values are model specific.
+.PP
+\fB--soc-slider-offset #\fP write the numeric value to the Soc Slider Offset.
+The slider offset is the maximum value that software allows the SoC to
+autonomously add to the SoC Slider to improve energy efficiency.
+The value 0 prohibits the SoC from autonomously changing the slider.
+.PP
+\fB--platform-profile <name>"\fP set the platform profile to <name>.
+Available choices are in platform-profile-0/choices.  The Soc Slider
+driver currently supports "low-power", "balanced", and "performance".
