PROTOCOLS
Dsi
Defined in fuchsia.hardware.dsi/dsi.banjo
Connect
This function takes the server end of a FIDL connection that will serve fuchsia.hardware.dsi.
This is meant to be used by the display driver. This connection will stay open and valid throughout the lifecycle of the display driver.
The protocol only accepts one client at a time. Returns ZX_OK upon successful connection.
