+ This option enables device driver support for the PWM channels
+ on the Cirrus EP93xx processors. The EP9307 chip only has one
+ PWM channel all the others have two, the second channel is an
+ alternate function of the EGPIO14 pin. A sysfs interface is
+ provided to control the PWM channels.

+ To compile this driver as a module, choose M here: the module will
