* The internal PD of VOP2 on rk3588 take effect immediately
* for power up and take effect by vsync for power down.
*
* And the PD_CLUSTER0 is a parent PD of PD_CLUSTER1/2/3,
* we may have this use case:
* Cluster0 is attached to VP0 for HDMI output,
* Cluster1 is attached to VP1 for MIPI DSI,
* When we enable Cluster1 on VP1, we should enable PD_CLUSTER0 as
* it is the parent PD, event though HDMI is plugout, VP1 is disabled,
* the PD of Cluster0 should keep power on.
* When system go to suspend:
* (1) Power down PD of Cluster1 before VP1 standby(the power down is take
* effect by vsync)
* (2) Power down PD of Cluster0
*
* But we have problem at step (2), Cluster0 is attached to VP0. but VP0
* is in standby mode, as it is never used or hdmi plugout. So there is
* no vsync, the power down will never take effect.
* According to IC designer: We must power down all internal PD of VOP
* before we power down the global PD_VOP.
* So we get this workaround:
* If we found a VP is in standby mode when we want power down a PD is
* attached to it, we release the VP from standby mode, than it will
* run a default timing and generate vsync. Than we can power down the
* PD by this vsync. After all this is done, we standby the VP at last.
