[ Upstream commit 1342b5b23da9559a1578978eaff7f797d8a87d91 ]

If the component driver fails to bind, or is unbound, the driver data
for the top-level platform device points to a freed drm_device. If the
system is then suspended, the driver passes this dangling pointer to
drm_mode_config_helper_suspend(), which crashes.

Fix this by only setting the driver data while the platform driver holds
a reference to the drm_device.

<title>drm/sun4i: Remove obsolete references to PHYS_OFFSET</title>

<content type='text'>
commit b4bdc4fbf8d0 ("soc: sunxi: Deal with the MBUS DMA offsets in a
central place") added a platform device notifier that sets the DMA
offset for all of the display engine frontend and backend devices.

The code applying the offset to DMA buffer physical addresses was then
removed from the backend driver in commit 756668ba682e ("drm/sun4i:
backend: Remove the MBUS quirks"), but the code subtracting PHYS_OFFSET
was left in the frontend driver.

As a result, the offset was applied twice in the frontend driver. This
likely went unnoticed because it only affects specific configurations
(scaling or certain pixel formats) where the frontend is used, on boards
with both one of these older SoCs and more than 1 GB of DRAM.

In addition, the references to PHYS_OFFSET prevent compiling the driver
on architectures where PHYS_OFFSET is not defined.

Pull driver core updates from Greg KH:
 "Here is the set of driver core changes for 5.18-rc1.

  Not much here, primarily it was a bunch of cleanups and small updates:

   - kobj_type cleanups for default_groups

   - documentation updates

   - firmware loader minor changes

   - component common helper added and take advantage of it in many
     drivers (the largest part of this pull request).

  All of these have been in linux-next for a while with no reported
  problems"

It turns out that DE3 manual has inverted YUV and YVU format numbers for
P010 and P210. Invert them.

This was tested by playing video decoded to P010 and additionally
confirmed by looking at BSP driver source.

The sun4i KMS driver will call drm_plane_create_zpos_property() with an
init value depending on the plane type.

Since the initial value wasn't carried over in the state, the driver had
to set it again in sun4i_backend_layer_reset().
However, the helpers have been adjusted to set it properly at reset, so
this is not needed anymore.
