nordic,nrf-auxpll
Vendor: Nordic Semiconductor
Note
An implementation of a driver matching this compatible is available in drivers/clock_control/clock_control_nrf_auxpll.c.
Description
Nordic Auxiliary PLL (Phase Locked Loop)
The output frequency (f_out) of the auxiliary PLL is calculated as follows:
f_out = ((R + A * 2^(-16)) * f_src) / B
where:
- A: nordic,frequency
- B: nordic,outdiv
- R: nordic,range (3=low, 4=mid, 5=high, 6=statichigh)
- f_src: Source frequency, given by clocks

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
