From e52e15d3c153b88c4536cf18214fac18481c888a Mon Sep 17 00:00:00 2001 From: Ondrej Zajicek Date: Fri, 16 Mar 2007 13:38:16 -0800 Subject: [PATCH] [PATCH] sstfb: fix pixclock setting on Voodoo 1/2 cards Pixclock setting in sstfb didn't work with my Voodoo 2 card with ICS 5342 DAC (this DAC requires two consecutive writes to one of its registers to program pixclock - maybe first write merged with second).
