CONFIG_CLOCK_CONTROL_NRF_CALIBRATION_LF_ALWAYS_ON

LF clock is always on

Type: bool

Help

If RTC is used as system timer then LF clock is always on and handling
can be simplified.

Direct dependencies

CLOCK_CONTROL_NRF_K32SRC_RC_CALIBRATION && CLOCK_CONTROL_NRF && CLOCK_CONTROL

(Includes any dependencies from ifs and menus.)

Default

y if NRF_RTC_TIMER

Kconfig definition
