phy: rockchip-inno-usb2: delay suspending phy if plug out device

The otg_sm_work will suspend the usb2 phy immediately
if it detects disconnection from host. However, the usb2
controller(e.g. DWC2) may need to reinit registers and
reset usb core after usb disconnect, and it needs to
keep the usb2 phy stay in power on state to get utmi clk
for these usb controller operation. We don't have a good
synchronization mechanism to operate usb2 phy between
usb2 phy driver and usb2 controller driver, so we delay
4s to suspend phy if detect otg device disconnect from
host, this can make sure that usb2 controller completes
reinitialization before suspend usb2 phy.

and real PWM state.

Use pwm_get_args() when the PWM user wants to retrieve this reference

UPSTREAM: drm/rockchip: Replace custom wait_for_vblanks with helper

Currently the driver uses a custom function to wait for flip to complete
after an atomic commit. It was needed before because of two problems:
 - there is no hardware vblank counter, so the original helper would
   have a race condition with the vblank interrupt,
 - the driver didn't support unreferencing cursor framebuffers
   asynchronously to the commit, which was what the helper expected.
Since both problems have been solved by previous patches, we can now
make the driver use the generic helper and remove custom waiting code.

legacy cursor API, which requires the updates to be fully asynchronous.

UPSTREAM: drm/rockchip: Avoid race with vblank count increment

Since VOP does not have a hardware vblank count register, the ongoing
commit might be racing with a requested vblank interrupt, which would
increment the software vblank counter before the changes being committed
actually happen.

To avoid this, we can extend .atomic_flush(), so after it sets cfg_done
bit, it polls the vblank interrupt bit until it's inactive to make sure
that any old vblank interrupt gets to the handler and then uses
synchronize_irq(vop->irq) to make sure the handler finishes running.

The polling case should happen very rarely, but even if, the total wait
time should be relatively low and in practice almost equal to the vop
hardirq handler running time.

UPSTREAM: coccinelle: catch krealloc() on devm_*() allocated memory

krealloc() must not be used against devm_*() allocated
memory regions:

- if a bigger memory is to be allocated, krealloc() and
  __krealloc() could return a different pointer than the
  one given to them, creating a memory region which is not
  managed, thus it will not be automatically released on
  device removal.

- if a bigger memory is to be allocated, krealloc() could
  kfree() the managed memory region which is passed to it.
  The old pointer is left registered as a resource for the
  device. On device removal, this dangling pointer will be
  used and an unrelated memory region could be released.

- if the requested size is equal to 0, krealloc() can also
  just behave like kfree(). Here too, the old pointer is
  kept associated with the device. On device removal, this
  invalid pointer will be used and an unrelated memory
  region could be released.

For all these reasons, krealloc() must not be used on a
pointer returned by devm_*() functions.
