- menuconfig GENERIC_PWM
- tristate "PWM Support"
- depends on SYSFS
- help
- This enables PWM support through the generic PWM library.
- If unsure, say N.

- tristate "Atmel AT32/AT91 PWM support"
- depends on AVR32 || ARCH_AT91
- help
- This option enables device driver support for the PWMC
- peripheral channels found on certain Atmel processors.
- Pulse Width Modulation is used many for purposes, including
- software controlled power-efficient backlights on LCD
- displays, motor control, and waveform generation. If
- unsure, say N.
- config GPIO_PWM
- tristate "PWM emulation using GPIO"
- help
- This option enables a single-channel PWM device using
- a kernel interval timer and a GPIO pin. If unsure, say N.
