imx8mm CLKOUT1/2 not working

I want to test some internal clocks using CLKOUT1/2 outputs. The only information I found is in

CCM_ANALOG_ANAMIX_PLL_MNIT_CTL register.

Despite selecting clock, divide value and setting output enable in this register, there is no signal on the output.

Is there something more that has to be done to make it work? Some device tree changes?

There is similar thread, but it's unresolved and inactive:
