+== ST SPEAr SoC PWM controller ==
+
+Required properties:
+- compatible: should be one of:
+  - "st,spear320-pwm"
+  - "st,spear1340-pwm"
+- reg: physical base address and length of the controller's registers
+- #pwm-cells: number of cells used to specify PWM which is fixed to 2 on
+  SPEAr. The first cell specifies the per-chip index of the PWM to use and
+  the second cell is the period in nanoseconds.
+
+Example:
+
+        pwm: pwm@a8000000 {
+            compatible ="st,spear320-pwm";
+            reg = <0xa8000000 0x1000>;
+            #pwm-cells = <2>;
+        };
