-pwm regulator bindings
+Bindings for the Generic PWM Regulator
+======================================
+
+Currently supports 2 modes of operation:
+
+Voltage Table:		When in this mode, a voltage table (See below) of
+			predefined voltage <=> duty-cycle values must be
+			provided via DT. Limitations are that the regulator can
+			only operate at the voltages supplied in the table.
+			Intermediary duty-cycle values which would normally
+			allow finer grained voltage selection are ignored and
+			rendered useless.  Although more control is given to
+			the user if the assumptions made in continuous-voltage
+			mode do not reign true.
+
+Continuous Voltage:	This mode uses the regulator's maximum and minimum
+			supplied voltages specified in the
+			regulator-{min,max}-microvolt properties to calculate
+			appropriate duty-cycle values.  This allows for a much
+			more fine grained solution when compared with
+			voltage-table mode above.  This solution does make an
+			assumption that a %50 duty-cycle value will cause the
+			regulator voltage to run at half way between the
+			supplied max_uV and min_uV values.
 
 Required properties:
-- compatible: Should be "pwm-regulator"
-- pwms: OF device-tree PWM specification (see PWM binding pwm.txt)
-- voltage-table: voltage and duty table, include 2 members in each set of
-  brackets, first one is voltage(unit: uv), the next is duty(unit: percent)
+--------------------
+- compatible:		Should be "pwm-regulator"
+
+- pwms:			PWM specification (See: ../pwm/pwm.txt)
+
+Only required for Voltage Table Mode:
+- voltage-table: 	Voltage and Duty-Cycle table consisting of 2 cells
+			    First cell is voltage in microvolts (uV)
+			    Second cell is duty-cycle in percent (%)
+
+NB: To be clear, if voltage-table is provided, then the device will be used
+in Voltage Table Mode.  If no voltage-table is provided, then the device will
+be used in Continuous Voltage Mode.
