The component driver only provides 'bind' and 'unbind' callbacks to tell
the host driver that it is time to assemble the aggregate driver now
that all the components have probed. The component driver model doesn't
attempt to resolve runtime PM or suspend/resume ordering, and explicitly
mentions thi
The device lists are poorly ordered when the component device code is
used. This is because component_master_add_with_match() returns 0
regardless of component devices calling component_add() first. It can
really only fail if an allocation fails, in which case everything is
going bad and we're out
This allows aggregate driver writers to use the device passed to their
probe/remove/shutdown functions properly instead of treating it as an
opaque pointer.

Similar to drm_of_component_probe() but using the new API that registers
a driver instead of an ops struct. This allows us to migrate the users
of drm_of_component_probe() to the new way of doing things.

CMDQ is used to update display register in vblank period, so
it should be execute in next 2 vblank. One vblank interrupt
before send message (occasionally) and one vblank interrupt
after cmdq done. If it fail to execute in next 3 vblank,
