| D | pwm-samsung.txt | 1 * Samsung PWM timers
3 Samsung SoCs contain PWM timer blocks which can be used for system clock source
4 and clock event timers, as well as to drive SoC outputs with PWM signal. Each
5 PWM timer block provides 5 PWM channels (not all of them can drive physical
6 outputs - see SoC and board manual).
