AM3715 IVA problem : off mode issue and register mapping issue

Other Parts Discussed in Thread: AM3715

Hi,

I am developing android using AM3715 and TI android 2.3.4 SDK v2.1,
I have 2 questions and need help:

1. How to disable IVA in AM3715, even it's not exist?.

Now I am debug suspend/resume issue (we are using AM3715), I found the system will not get into off mode "sometimes" when IVA2.2 is not hit off status, and it will cause dss,usb,per,core domain can't hit off too. I have tried some patchs and settings to stop IVA but without success, and check TRM, the 4 domain have dependency on IVA, but, IVA is not exist in AM3715, why I can see it in cat /debug/pm_debug/count? and it can hit off mode sometimes?

Does anyone know how to turn it off?

2. IVA2 register address error? why?

During the off mode debug, I cat the debug/pm_debug/register/1 then found the IVA address is wrong, it should be 48004000, but become 48104000? how to fix it?
