+TI/National Semiconductor LP3943 PWM controller
+
+Required properties:
+  - compatible: "ti,lp3943-pwm"
+  - #pwm-cells: Should be 2. See pwm.txt in this directory for a
+                description of the cells format.
+                Note that this hardware limits the period length to the
+                range 6250~1600000.
+  - ti,pwm0 or ti,pwm1: Output pin number(s) for PWM channel 0 or 1.
+    0 = output 0
+    1 = output 1
+    .
+    .
+    15 = output 15
+
+Example:
+PWM 0 is for RGB LED brightness control
+PWM 1 is for brightness control of LP8557 backlight device
