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.
