drm/amdgpu: don't finish the ring if not initialized

If a ring is not initialized, it also should not be finished.
For example, in Vega10's SR-IOV environment, UVD's decode ring is not
initialized, but will be finnished in amdgpu_uvd_sw_fini, because UVD
driver put all the uvd decode ring's finish operation into
amdgpu_uvd_sw_fini function, while not uvd_vXXX_0_sw_fini. This will
lead to amdgpu module unloading failure.

drm: Handle properties in the core for atomic drivers

The reason behind the original indirection through the helper
functions was to allow existing drivers to overwrite how they handle
properties. For example when a vendor-specific userspace had
expectations that didn't match atomic. That seemed likely, since
atomic is standardizing a _lot_ more of the behaviour of a kms driver.

But 20 drivers later there's no such need at all. Worse, this forces
all drivers to hook up the default behaviour, breaking userspace if
they forget to do that. And it forces us to export a bunch of core
function just for those helpers.

And finally, these helpers are the last places using
drm_atomic_legacy_backoff() and the implicit acquire_ctx.

This patch here just implements the new behaviour and updates the
docs. Follow-up patches will garbage-collect all the dead code.

v2: Fixup docs even better!

v3: Make it actually work ...

v4: Drop the uses_atomic_modeset() checks from the previous patch
again, since they're now moved up in the callchain.

drm: Don't update property values for atomic drivers

Atomic drivers only use the property value store for immutable (i.e.
can't be set by userspace, but the kernel can still adjust it)
properties. The only tricky part is the removal of the update in
drm_atomic_helper_update_legacy_modeset_state().

This was added in

    drm/i915: update dpms property in set_mode

for the legacy modeset code. The reason we needed this hack was that
i915 didn't yet set DRIVER_ATOMIC, and we checked for that instead of
the newer-ish drm_drv_uses_atomic_modeset(), which avoids such
troubles. With the correct feature checks this isn't needed anymore at
all.

Also make sure that drivers don't accidentally get this wrong by
making the exported version of drm_object_property_get_value() only
work for legacy drivers. Only gma500 uses it anyway.

drm/omap: Rework the rotation-on-crtc hack

I want/need to rework the core property handling, and this hack is

As *some* of the HDMI 2.0 PHYs have the same register layout as the 3D

and still let user overwrite this with custom configuration function

If, for some reason, the PHY is custom or has a register different

in order for the system to work correctly. As we prefer the pdata

will not make any impact in custom platforms.

drm/bridge: dw-hdmi: add better clock disable control

The video setup path aways sets the clock disable register to a specific
value, which has the effect of disabling the CEC engine.  When we add the
CEC driver, this becomes a problem.

Fix this by only setting/clearing the bits that the video path needs to.
