关于AM3354内核主频1G的设置

Other Parts Discussed in Thread: TPS65910

我通过tps65910设置VDD_MPU来修改电压,使CPU工作在1G。

在uboot下,修改设置后,VDD1可以成功设置成1.325V,但是进入Linux系统后又改回了1.2V,应该是内核代码又修改回了720M主频。

参照文档《AM335x Linux Power Management User Guide》,发现目前的3.2.0内核版本不支持800M 和1G的主频。

如下:

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
275000 500000 600000 720000

请问,怎样能将800000 和1000000加入内核设置。

我的CPU是AM3354BZCZA100
