From f62b123813ea604d16ed6115fe2fa552b23d9102 Mon Sep 17 00:00:00 2001 From: Tang Yuantian Date: Fri, 6 Sep 2013 10:45:40 +0800 Subject: [PATCH] powerpc/mpc85xx: Fix the I2C bus speed error on p1022 The source clock frequency of I2C bus on p1022 is the platform(CCB) clock, not CCB/2. The wrong source clock frequency leads to wrong I2C bus speed setting. so, fixed it.
