/* Constant: UDI_GFX_PROP_ENABLE
*
* Valid values:
* 0 - disabled

+ * 2 - reset
*
* Ranges:
- * Hardwired 1, or 0-1
- *
- * The connector or engine is enabled (nonzero) or disabled (zero). A disabled
- * engine forwards all data from the previous stage unmodified. A disabled
- * connector does not send any data over the connector. Drivers may power down
- * the physical counterparts of disabled components to preserve power, and users
- * should expect delays when enabling connectors or components representing
- * framebuffers. Disabling is however not recommended for sprite layers, which
- * may repeatedly be enabled and disabled. A disabled component can still have
- * its state changed, and the driver must complete all commands and other state
- * changes as expected, regardless of disabled or power state. The valid ranges
- * reported for this property may be 1 (always enabled) or 0-1 (either enabled
- * or disabled).
+ * Must include at least 1
+ *
+ * The primary state of the connector or engine. An enabled state indicates
+ * it is functioning and generating live output. A disabled state is one where
+ * it is not contributing to any output but is otherwise functional. Finally
+ * the reset state is where the driver is free to deallocate all resources
+ * corresponding to this component and trash any state not referenced by other
+ * components.
+ *
+ * A disabled or reset engine forwards all data from the previous stage
+ * unmodified. The disabled state indicates that the component might be
+ * returned to its enabled state within short notice.
+ *
+ * A disabled connector will not send pixel data, but can perform other
+ * initialisation communication such as DDC. A reset connector will not respond
+ * in any fashion and can not be used for other purposes. Hardware is expected
+ * to be powered down in such state.
+ *
+ * Users should expect significant delays when moving components in and out of
+ * the reset state. Moving engines between the enabled and disabled state should
+ * take effect within one frame, such transition should take effect on a frame
+ * boundary when supported.
