nordic,nrf-hsfll
Vendor: Nordic Semiconductor
Note
An implementation of a driver matching this compatible is available in drivers/clock_control/clock_control_nrf2_hsfll.c.
Description
Nordic nRF HSFLL
The HSFLL mixed-mode IP generates several clock frequencies in the range from
64 MHz to 400 MHz (in steps of 16 MHz).
Usage example:
hsfll: clock@deadbeef {
compatible = "nordic,nrf-hsfll";
reg = <0xdeadbeef 0x1000>;
clocks = <&fll16m>;
clock-frequency = <DT_FREQ_M(320)>;
nordic,ficrs = <&ficr NRF_FICR_TRIM_APPLICATION_HSFLL_TRIM_VSUP>,
<&ficr NRF_FICR_TRIM_APPLICATION_HSFLL_TRIM_COARSE_0>,
<&ficr NRF_FICR_TRIM_APPLICATION_HSFLL_TRIM_FINE_0>;
nordic,ficr-names = "vsup", "coarse", "fine";
};
Required FICR entries are for VSUP, COARSE and FINE trim values.

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.
