[PATCH] mfd: SM501 core driver
This driver provides the core functionality of the SM501, which is a multi-function chip including two framebuffers, video acceleration, USB, and many other peripheral blocks. The driver exports a number of entries for the peripheral drivers to use.

This is the core driver for the Silicon Motion SM501 multimedia
|
||||
companion chip. This device is a multifunction device which may
|
||||
provide numerous interfaces including USB host controller USB gadget,
|
||||
Asyncronous Serial ports, Audio functions and a dual display video
|
||||
interface. The device may be connected by PCI or local bus with
|
||||
varying functions enabled.
