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. Signed-off-by: Caesar Wang <wxt@xxxxxxxxxxxxxx> --- Changes in v16: - Add more domain decription.
