13 The clock architecture in MediaTek like below
14 PLLs -->
15 dividers -->
16 muxes
17 -->
18 clock gate
19
20 The apmixedsys provides most of PLLs which generated from SoC 26m.
21 The topckgen provides dividers and muxes which provide the clock source to other IP blocks.
22 The infracfg_ao provides clock gate in peripheral and infrastructure IP blocks.
23 The mcusys provides mux control to select the clock source in AP MCU.
24 The device nodes also provide the system control capacity for configuration.
