Deprecate support for configuring the MCO source and prescaler from Kconfig configurations. This is now done by devicetree and an MCO driver instead, which also configures the pin to be used by the MCO peripheral. Signed-off-by: Joakim Andersson <joerchan@gmail.com>

Size of the LSI measurement window (# of LSI periods)
|
|
|
|
The measurement process involves waiting for a certain amount of LSI periods
|
|
to occur, in order to determine precisely the LSI period, and thus frequency.
|
|
|
|
This property controls how much LSI periods are required for each measure.
|
|
Bigger window sizes increase accuracy of the measure, but increase the time
|
|
needed to complete it. Since fLSI >= 24kHz, increasing the measurement window
|
|
size makes each measure roughly 42µs slower in the worst case.
|
|
|
|
Minimal value is a recommendation from RM0505 Rev.1 §25.8.2, and maximum
|
|
value is a hardware limitation.

help
|
|
Interval at which runtime measurements should be performed, in milliseconds
|
|
|
|
Since the LSI RC frequency is affected by temperature, which is not stable
|
|
across time, it is recommended to perform measurements of the LSI frequency
|
|
at regular intervals to obtain better accuracy.
|
|
|
|
This property enables runtime LSI measurement if present. In this case,
|
|
a background thread is created and performs LSI measurements, sleeping
|
|
the amount of time specified in this property between each measure. This
|
|
thread is also tasked with updating the control registers of peripherals
|
|
affected by slow clock drift such as RTC or IWDG, in collaboration with
|
|
the peripherals' drivers. Note that this increases the memory footprint
|
|
of the clock control driver, and may increase power consumption.
|
|
|
|
Setting this option to the default value of "0" disables runtime frequency
|
|
measurements - the result of a single measure performed at boot will be
|
|
treated as LSI frequency for the lifetime of the application.
