2011-11-16 Thread Zhao Chenhui
From: Li Yang Some 85xx silicons like MPC8536 and P1022 has the JOG PM feature. The patch adds the support to change CPU frequency using the standard cpufreq interface. Add the all PLL ratio core support. The ratio CORE to CCB can 1:1(except MPC8536), 3:2, 2:1, 5:2, 3:1, 7:2 and 4:1. Signed-off
