From 2ad3aba01d37b72e7c957b07e102fccd64fe6d13 Mon Sep 17 00:00:00 2001 From: Jeffrey Mann Date: Thu, 12 Apr 2007 14:15:59 +0200 Subject: [PATCH] ppc4xx: Fix i2c divisor calcularion for PPC4xx This patch fixes changes the i2c_init(...) function to use the function get_OPB_freq() rather than calculating the OPB speed by sysInfo.freqPLB/sysInfo.pllOpbDiv. The get_OPB_freq() function is specific per processor. The prior method was not and so was calculating the wrong speed for some PPC4xx processors.
