Merge drm/drm-next into drm-intel-gt-next

Maarten requested a backmerge due his work depending on subtle semantic
changes introduced by:

  7e2e69ed4678 ("drm/i915: Fix i915_request fence wait semantics")
  2cbb8d4d6770 ("drm/i915: use new iterator in i915_gem_object_wait_reservation")

Both should probably have been merged to drm-intel-gt-next anyway.

+  The nt35950 IC from Novatek is a Driver IC used to drive MIPI-DSI panels,
+  with Static RAM for content retention in command mode and also supports
+  video mode with VESA Frame Buffer Compression or Display Stream Compression
+  on single, or dual dsi port(s).
+  This DDIC is also capable of upscaling an input image to the panel's native
+  resolution, for example it can upscale a 1920x1080 input to 3840x2160 with
+  either bilinear interpolation or pixel duplication.

+--------------------------------------------------------------------------------------
+
+The values in struct drm_mode_config.{max_width,max_height} describe the
+maximum supported framebuffer size. It's the virtual screen size, but many
+drivers treat it like limitations of the physical resolution.
+
+The maximum width depends on the hardware's maximum scanline pitch. The

+ *
+ *	"privacy-screen hw-state" is read-only and reflects the actual state

+ *	"Enabled-locked", "Disabled-locked". The locked states indicate
+ *	that the state cannot be changed through the DRM API. E.g. there
+ *	might be devices where the firmware-setup options, or a hardware
+ *	slider-switch, offer always on / off modes.
+ *
+ *	"privacy-screen sw-state" can be set to change the privacy-screen state
+ *	when not locked. In this case the driver must update the hw-state
+ *	property to reflect the new state on completion of the commit of the
+ *	sw-state property. Setting the sw-state property when the hw-state is
+ *	locked must be interpreted by the driver as a request to change the
+ *	state to the set state when the hw-state becomes unlocked. E.g. if
+ *	"privacy-screen hw-state" is "Enabled-locked" and the sw-state
+ *	gets set to "Disabled" followed by the user unlocking the state by
+ *	changing the slider-switch position, then the driver must set the
+ *	state to "Disabled" upon receiving the unlock event.
+ *
+ *	In some cases the privacy-screen's actual state might change outside of
+ *	control of the DRM code. E.g. there might be a firmware handled hotkey
+ *	which toggles the actual state, or the actual state might be changed
+ *	through another userspace API such as writing /proc/acpi/ibm/lcdshadow.
+ *	In this case the driver must update both the hw-state and the sw-state
+ *	to reflect the new value, overwriting any pending state requests in the
+ *	sw-state. Any pending sw-state requests are thus discarded.
+ *
+ *	Note that the ability for the state to change outside of control of
+ *	the DRM master process means that userspace must not cache the value
+ *	of the sw-state. Caching the sw-state value and including it in later
+ *	atomic commits may lead to overriding a state change done through e.g.
+ *	a firmware handled hotkey. Therefor userspace must not include the
+ *	privacy-screen sw-state in an atomic commit unless it wants to change
