drm/connector: Add support for privacy-screen properties (v4)
Add support for generic electronic privacy screen properties, that
can be added by systems that have an integrated EPS.
Changes in v2 (Hans de Goede)
- Create 2 properties, "privacy-screen sw-state" and
"privacy-screen hw-state", to deal with devices where the OS might be
locked out of making state changes
- Write kerneldoc explaining how the 2 properties work together, what
happens when changes to the state are made outside of the DRM code's
control, etc.
Changes in v3 (Hans de Goede)
- Some small tweaks to the kerneldoc describing the 2 properties
Changes in v4 (Hans de Goede)
- Change the "Enabled, locked" and "Disabled, locked" hw-state enum value
names to "Enabled-locked" and "Disabled-locked". The xrandr command shows
all possible enum values separated by commas in its output, so having a
comma in an enum name is not a good idea.
- Do not add a privacy_screen_hw_state member to drm_connector_state
since this property is immutable its value must be directly stored in the
obj->properties->values array
