# # PWM infrastructure and devices # menuconfig GENERIC_PWM tristate "PWM Support" depends on SYSFS help This enables PWM support through the generic PWM library. If unsure, say N. if GENERIC_PWM config ATMEL_PWM 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. endif
