nordic,nrf-hsfll

Vendor: Nordic Semiconductor

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.
