When video port output image under 4K@60Hz(dclk less than 600MHz),
The dclk parent use hdmi0 phy pll or hdmi1 phy pll. In some cases
the hdmi0 phy pll or hdmi1 phy pll is not enough for all output
interface. For example, hdmi0 and hdmi0 connect to video port0 and
dp connect to video port1. In this case, It need the video port1
need use default dclk parent.

Quickly plug and unplug the Type-C device with DP function test, there
is a low probability of unplugging the Type-C dongle, DP work cannot
acquire the mutex(port->lock), and it will always be stuck in the
tcpm_unregister_altmodes() function during the rest port process, causing
the Type-C device to be inserted again to fail to be detected or the reboot
system to be stuck. The exception process is as follows:
(1) Thread#1: unplug the Type-C device to trigger cc status changes interrupt, in the
tcpm_pd_event_handler() function, first acquire the mutex(port->lock),
then start state_machine work, and finally release the mutex(port->lock);
tcpm_cc_change()
-->tcpm_pd_event_handler()
-->mutex_lock(&port->lock) /* step 1 */
-->_tcpm_cc_change(port, cc1, cc2) /* step 2 */
-->tcpm_set_state(port, SRC_UNATTACHED, 0)
-->kthread_queue_work(port->wq, &port->state_machine) /* step 3 */
--> mutex_unlock(&port->lock) /* step 4 */
(2) Thread#2: before the execution of "step 2" is completed, DP work calls
the callback function registered by the tcpm framework to initiate a VDM
Message, such as Enter Mode Message, in the tcpm_queue_vdm_unlocked()
acquires the mutex(port->lock) fails and goes to sleep;
dp_altmode_work()
--> typec_altmode_enter(dp->alt)
--> tcpm_altmode_enter()
--> tcpm_queue_vdm_unlocked()
--> mutex_lock(&port->lock) /* dp work enter sleep */
(3) After step 4, tcpm_queue_vdm_unlocked() did not acquire for the mutex
(port->lock), but was preempted by the state_machine work to enter the reset
port process. In the reset port process, call the tcpm_unregister_altmodes()
function to release altmode and cancel dp work. Because tcpm_queue_vdm_unlocked()
did not acquire the mutex(port->lock), causing it to be stuck in cancel dp work.
tcpm_state_machine_work()
-->mutex_lock(&port->lock)
-->tcpm_reset_port(port)
-->tcpm_unregister_altmodes(port)
......
--> dp_altmode_remove()
--> cancel_work_sync(&dp->work) /* always stuck in cancel dp work */
......
Therefore, after adding a new mutex to wait for the tcpm_pd_event_handler() function
to complete the processing, if the port is in the disconnect state, there is no need
to acquire the mutex(port->lock) in the tcpm_queue_vdm_unlocked() function.

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. bus 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:
We 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.
