VOYAGER(4)	    OpenBSD Programmer's Manual (Loongson)	    VOYAGER(4)

NAME
     voyager - Silicon Motion Mobile Multimedia Companion Chip

SYNOPSIS
     voyager* at pci?
     gpio0 at voyager?
     ohci* at voyager?
     smfb* at voyager?

DESCRIPTION
     The voyager driver supports the Silicon Motion SM502 MMCC device.

     This chip is intended to fulfill most of a modern laptop's I/O needs, and
     provides:

	   -   a 2D smfb(4) frame buffer with analog RGB and digital LCD panel
	       interfaces
	   -   an 8-bit parallel interface
	   -   a ohci(4) USB controller
	   -   two UART or IrDA ports
	   -   two Zoom Video interfaces
	   -   an AC97 or I2S audio codec
	   -   two Synchronous Serial Ports (SSP)
	   -   Pulse Width Modulation (PWM)
	   -   64 gpio(4) pins

     Not all the device interfaces are supported under OpenBSD.

     The ohci(4) component only attaches on Gdium Liberty systems with the
     older motherboard artwork design, as newer systems do not have this USB
     port connected to anything, causing an otherwise annoying long delay to
     probe the empty bus on boot.
