7 Oscillator Frequency Multiplier Clock (OFMCLK), which is derived from
8 High-Frequency Clock Generator (HFCG), is the source clock of Cortex-M4 core
11 Here is an example of configuring OFMCLK and the other clock sources derived
14 clock-frequency = <DT_FREQ_M(100)>; /* OFMCLK runs at 100MHz */
15 core-prescaler = <5>; /* CORE_CLK runs at 20MHz */
16 apb1-prescaler = <5>; /* APB1_CLK runs at 20MHz */
17 apb2-prescaler = <5>; /* APB2_CLK runs at 20MHz */
18 apb3-prescaler = <5>; /* APB3_CLK runs at 20MHz */
