According to a description from TRM, the following table lists
all the power domains.
------------------------ -------------------------
|VD_CORE | |VD_LOGIC | PD_VIO |
|xxxxxxxxxxxxxxxxxxxx | |xxxxxxxx -----------|
|xxxxxxxxxxxxxxxxxxxx | |xxxxxxxx |
|xxxxxxxxxxxxxxxxxxxx | | |
|xxxxxxxxxxxxxxxxxxxx | |--------- -----------|
| | |PD_PERI | | PD_VIDEO |
| | |--------- -----------|
| | |--------- -----------|
| | |PD_ALIVE | | PD_HEVC |
|---------- ---------- | |--------- -----------|
||PD_A17_1| |PD_A17_2| | -------------------------
|---------- ---------- | |VD_GPU |PD_GPU |
|---------- ---------- | -------------------------
||PD_A17_3| |PD_DEBUG| | -------------------------
|---------- ---------- | |VD_PMU |PD_PMU |
------------------------ -------------------------
VD_* : voltage domain
PD_* : power domain
At the moment, we can support some power-domain type on RK3288.
We can add more types on RK3288 in the future, that's need to do.
