Subject: [PATCH] savagefb: Speed up the I2C bus
Date: Tue, 12 Feb 2008 10:29:09 +0100 [thread overview]
Message-ID: <20080212102909.2749d2fd@hyperion.delvare> (raw)
There is no reason to drive the savagefb I2C bus 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, and so
are the legacy i2c-savage4 and i2c-prosavage drivers.
