Configure hardware PLL

how to set up PLL clocking hardware using registers? What does different types of PLL mean? (APLL, DPLL, etc.)
I’m trying to set up APLL clocking(expecting that this will increase the frequency of the entire core) using registers and based on reference manual rk3568 (2.8.1 on page 169) but writing to registers does not even occur. Can you help me with advice on how to act?

Did you wait for the PLL to work?
