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

+ * 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

+ *
+ * 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
