|
|
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 provides clock gate in peripheral and infrastructure IP blocks.
|
|
The mcusys provides mux control to select the clock source in AP MCU.
|
|
The device nodes also provide the system control capacity for configuration.
