7 title: Samsung SoC PWM timers
10   - Thierry Reding <thierry.reding@gmail.com>

14   Samsung SoCs contain PWM timer blocks which can be used for system clock source
15   and clock event timers, as well as to drive SoC outputs with PWM signal. Each
16   PWM timer block provides 5 PWM channels (not all of them can drive physical
17   outputs - see SoC and board manual).
