     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).
     18
     19  Be aware that the clocksource driver supports only uniprocessor systems.

     42      - "pwm-tclk0" - first external PWM clock source,
     43      - "pwm-tclk1" - second external PWM clock source.
     44      Note that not all IP variants allow using all external clock sources.
     45      Refer to SoC documentation to learn which clock source configurations
     46      are available.
