  18           This option enables device driver support for the PWMC
  19           peripheral channels found on certain Atmel processors.
  20           Pulse Width Modulation is used many for purposes, including
  21           software controlled power-efficient backlights on LCD
  22           displays, motor control, and waveform generation.  If
  23           unsure, say N.

  28          This option enables a single-channel PWM device using
  29          a kernel interval timer and a GPIO pin.  If unsure, say N.
