clk_ref_freq published anywhere ?

[mschnell1]

I found where TIMER0 is initialized in embassy and this involves setting the clock source in embassy/embassy-rp/src/clocks.rs.
Now I want to initialize TIMER1 (and decently use clock sources for other peripherals).
I seemingly should use the clk_ref_freq defined in embassy/embassy-rp/src/clocks.rs to calculate appropriate factors in a similar way as done for TIMER0. But I don't find a way to access this value. (Right now I calculate clk_ref_freq by reading back the factor from TIMER0:

let clk_ref_freq = pac::TICKS.timer0_cycles().read().0 * 1000000;

Nasty hack :) )
Is there an "official" way to get clk_ref_freq or another appropriate constant (derived from the Oscillator frequency)? I did not find anything in the documentation.

Also see #3766

This said, IMHO there should be settable "features" defining the desired CPU clock (defaulting to the official max clock of the RP2040 rsp RP235x) and defining the crystal frequency (defaulting to what the BSP defines),
Will this affect the multiple "magic numbers" in fn crystal() fn rosc() etc ?

finally found it:
embassy_rp::clocks::clk_ref_freq()
