45 	  Enable driver for STM32 clock mux which don't match an
46 	  existing clock hardware block but allows to select a clock
47 	  for a specific domain. For instance per_ck clock on STM32H7 or

72 	int "LSI run-time measurement interval (ms)"
77 	  Since the LSI RC frequency is affected by temperature, which is not stable
78 	  across time, it is recommended to perform measurements of the LSI frequency
85 	  affected by slow clock drift such as RTC or IWDG, in collaboration with
87 	  of the clock control driver, and may increase power consumption.
89 	  Setting this option to the default value of "0" disables runtime frequency
90 	  measurements - the result of a single measure performed at boot will be
91 	  treated as LSI frequency for the lifetime of the application.
