From 819062219abf8a78e54cad5c1c8716e6c8e7b870 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Sat, 23 Jun 2007 17:16:30 -0700 Subject: SM501: Clock updates and checks Ensure that the M1XCLK and MCLK are sourced from the same PLL (and refuse to bind the driver if they are not). Update the PCI to safe initialisation values, as 72MHz is the maximum clock for 33MHz PCI bus mastering.
