zx::result<std::unique_ptr<DisplayEngine>> Create (std::shared_ptr<fdf::Namespace> incoming, display::DisplayEngineEventsInterface * engine_events, structured_config::Config structured_config)

Factory method for production use.

`incoming` must be non-null.

`engine_events` must not be null and must outlive `DisplayEngine`.

void DisplayEngine (std::shared_ptr<fdf::Namespace> incoming, display::DisplayEngineEventsInterface * engine_events, structured_config::Config structured_config)

Creates an uninitialized `DisplayEngine` instance.

`incoming` must be non-null.

`engine_events` must not be null and must outlive `DisplayEngine`.

Production code should use `DisplayEngine::Create()` instead.

zx_status_t Initialize ()

Acquires parent resources and sets up display submodules.

Must be called exactly once via the `Create()` factory method during

the DisplayEngine lifetime in production code.

TODO(https://fxbug.dev/42082357): Replace the two-step initialization with

a factory method and a constructor.

Defined at line 1159 of file ../../src/graphics/display/drivers/amlogic-display/display-engine.cc

void Deinitialize ()

Tears down display submodules and turns off the hardware.

Must be called before the DisplayEngine instance is destroyed in production code,

or called automatically by the destructor.

zx_status_t GetCommonProtocolsAndResources ()

Acquires the common protocols (pdev, sysmem and amlogic-canvas) and

resources (Vsync interrupts, capture interrupts and BTIs) from the parent

nodes.

Must be called once and only once per driver binding procedure, before

the protocols / resources mentioned above being used.

This is meant for private use, but is marked public because the unit test

needs to be able to call it as well to bypass the full `Initialize()` flow.
