+- clock-names: should contain all following required clock names:
+ - "timers" - PWM base clock used to generate PWM signals,
+ and any subset of following optional clock names:
+ - "pwm-tclk0" - first external PWM clock source,
+ - "pwm-tclk1" - second external PWM clock source.
+ Note that not all IP variants allow using all external clock sources.
+ Refer to SoC documentation to learn which clock source configurations
+ are available.
+- clocks: should contain clock specifiers of all clocks, which input names
+ have been specified in clock-names property, in same order.
