		description:
		A u32 value that represents the running time dynamic
		power coefficient in units of uW/MHz/V^2. The
		coefficient can either be calculated from power
		measurements or derived by analysis.

		The dynamic power consumption of the GPU is
		proportional to the square of the Voltage (V) and
		the clock frequency (f). The coefficient is used to
		calculate the dynamic power as below -

		Pdyn = dynamic-power-coefficient * V^2 * f

		where voltage is in V, frequency is in MHz.
