From d7636e0b0769e0f4f437ff33168d723f86e7c080 Mon Sep 17 00:00:00 2001 From: "apatard@mandriva.com" Date: Wed, 19 May 2010 10:44:14 +0200 Subject: staging: Add framebuffer driver for XGI chipsets This driver handles XG20, XG21, XG40, XG42 chipsets from XGI. They're also known as Z7,Z9,Z11 chipsets. It's based on the SiS fb driver but has been heavily modified by XGI to support their newer chipsets.
