Fudge Factors:			Fudge factors are used to boost demand for

				resources like bus bandswidth, clk rate etc. to

				overcome system inefficiencies and avoid any

				glitches. These fudge factors are expressed in

				terms of numerator and denominator. First value

				is numerator followed by denominator. They all

				are optional but highly recommended.

				Ex:

				x = value to be fudged

				a = numerator, default value is 1

				b = denominator, default value is 1

				FUDGE(x, a, b) = ((x * a) / b)

- qcom,mdss-ib-factor:		This fudge factor is applied to calculated ib

				values in default conditions.

- qcom,mdss-high-ib-factor:	This fudge factor is applied to calculated ib

				values. Use of this factor is determined by the

				driver and open new use-cases.

- qcom,mdss-clk-factor:		This fudge factor is applied to calculated mdp

				clk rate in default conditions.



Optional subnodes:

Child nodes representing the frame buffer virtual devices.
