pwm: New driver to support PWMs on TWL4030/6030 series of PMICs
The driver supports the following PWM outputs: TWL4030 PWM0 and PWM1 TWL6030 PWM1 and PWM2 On TWL4030 the PWM signals are muxed. Upon requesting the PWM the driver will select the correct mux so the PWM can be used. When the PWM has been freed the original configuration is going to be restored.

+Texas Instruments TWL series PWM drivers

+Supported PWMs:
+On TWL4030 series: PWM1 and PWM2
+On TWL6030 series: PWM0 and PWM1
+
+Required properties:
+- compatible: "ti,twl4030-pwm" or "ti,twl6030-pwm"
+- #pwm-cells: should be 2. The first cell specifies the per-chip index
+ of the PWM to use and the second cell is the period in nanoseconds.
+
+Example:
+
+twl_pwm: pwm {
+ compatible = "ti,twl6030-pwm";
+ #pwm-cells = <2>;
+};
