+/**
+ * DOC: Overview
+ *
+ * DC is the OS-agnostic component of the amdgpu DC driver.
+ *
+ * DC maintains and validates a set of structs representing the state of the
+ * driver and writes that state to AMD hardware
+ *
+ * Main DC HW structs:
+ *
+ * struct dc - The central struct. One per driver. Created on driver load,
+ * destroyed on driver unload.
+ *
+ * struct dc_context - One per driver.
+ * Used as a backpointer by most other structs in dc.
+ *
+ * struct dc_link - One per connector (the physical DP, HDMI, miniDP, or eDP
+ * plugpoints). Created on driver load, destroyed on driver unload.
+ *
+ * struct dc_sink - One per display. Created on boot or hotplug.
+ * Destroyed on shutdown or hotunplug. A dc_link can have a local sink
+ * (the display directly attached). It may also have one or more remote
+ * sinks (in the Multi-Stream Transport case)
+ *
+ * struct resource_pool - One per driver. Represents the hw blocks not in the
+ * main pipeline. Not directly accessible by dm.
+ *
+ * Main dc state structs:
+ *
+ * These structs can be created and destroyed as needed. There is a full set of
+ * these structs in dc->current_state representing the currently programmed state.
+ *
+ * struct dc_state - The global DC state to track global state information,
+ * such as bandwidth values.
+ *
+ * struct dc_stream_state - Represents the hw configuration for the pipeline from
+ * a framebuffer to a display. Maps one-to-one with dc_sink.
+ *
+ * struct dc_plane_state - Represents a framebuffer. Each stream has at least one,
+ * and may have more in the Multi-Plane Overlay case.
+ *
+ * struct resource_context - Represents the programmable state of everything in
+ * the resource_pool. Not directly accessible by dm.
+ *
+ * struct pipe_ctx - A member of struct resource_context. Represents the
+ * internal hardware pipeline components. Each dc_plane_state has either
+ * one or two (in the pipe-split case).
