Simple one-shot poll through the io_submit() interface. To poll for
a file descriptor the application should submit an iocb of type
IOCB_CMD_POLL. It will poll the fd for the events specified in the
the first 32 bits of the aio_buf field of the iocb.

->get_poll_head returns the waitqueue that the poll operation is going

Currently PSR flush is triggered from CRTC's .atomic_begin() callback,
which is executed after modeset disables and enables and before plane
updates are committed. Since PSR flush and re-enable can be triggered
asynchronously by external sources (input event, delayed work), it

It looks like the driver subsystem detaches devices from power domains
at shutdown without consent of the drivers. This means that we might have
our power domain turned off behind our back and the only way to avoid
problems is to stop doing any hardware programming at some

The first time after we call rockchip_drm_do_flush() after
rockchip_drm_psr_register(), we go from PSR_DISABLE to PSR_FLUSH. The
difference between PSR_DISABLE and PSR_FLUSH is whether or not we have a
delayed work pending - PSR is off in either state. However

It is not used anymore after last changes and it was not even correct to
begin with as it assumed a 1:1 relation between a CRTC and encoder,
while in fact a CRTC can be attached to multiple encoders.

Currently both rockchip_drm_psr_activate() and _deactivate() only set the
boolean "active" flag without actually making sure that hardware state
complies with it.
Since we are going to extend the usage of this API to properly lock PSR

When we enable bridge failed, we have to retry it, otherwise we would get

We currently wait for the panel to mirror our intended PSR state
before continuing on both PSR enter and PSR exit. This is really
only important to do when we're entering PSR, since we want to

Add a lock to vop to avoid disabling the crtc while waiting for a line
flag while enabling psr. If we disable in the middle of waiting for the
line flag, we'll end up timing out or worse.

Now that the spinlocks and timers are gone, we can remove the psr
worker located in rockchip's analogix driver and do the enable/disable
directly. This should simplify the code and remove races on disable.

Instead of using timer and spinlocks, use delayed_work and
mutexes for rockchip psr. This allows us to make blocking
calls when enabling/disabling psr (which is sort of important
given we're talking over dpcd to the display).
