From e0745ae7210c14e611a1fab2af820a4c2e447de5 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Mon, 28 Apr 2008 02:15:14 -0700 Subject: radeonfb: speed up the I2C buses There is no reason to drive the radeon I2C buses at such a low speed, so bump it from 12.5 kbps to 50 kbps. The Intel (i810) and Matrox framebuffer drivers already run their I2C bus at this speed. Signed-off-by: Jean Delvare Acked-by: Benjamin Herrenschmidt Cc: "Antonino A.
