description:
The clock architecture in Mediatek like below
PLLs -->
dividers -->
muxes
-->
clock gate
The apmixedsys provides most of PLLs which generated from SoC 26m.
The topckgen provides dividers and muxes which provide the clock source to other IP blocks.
The infracfg_ao and pericfg_ao provides clock gate in peripheral and infrastructure IP blocks.
