DM814x--想把ARM频率由原来的600MHZ改成1000MHZ,对应的CVDD_ARM要配置成1.35V,针对TPS65023BRSBR这个电源芯片,麻烦有了解的说下,感谢

Other Parts Discussed in Thread: TPS65911

在uboot中ARM频率相关分频值已经改好,但是电源需要配置成1.35v,uboot中默认的电源管理函数power_control( ) 是配置TPS65911这个芯片的,现在我板子上的电源管理芯片是TPS65023BRSBR,有哪位针对过这款芯片配置过的?我看了下这款芯片手册,其I2C地址的0X48,进入uboot中输入命令: i2c probe ,可以探测到这个地址,要是把CVDD_ARM配置成1.35V,我改怎样配置这款芯片中的寄存器?www.ti.com/.../tps65023b
