Subject: Re: [PATCH v3 0/4] powerpc: Open PIC binding and "pic-no-reset"

 From the feedback I have received so far, the fundamental ideas in this 
patch set are sane.  However, the following issues are still outstanding:

     1. What is the name of the no reset property?
        "pic-no-reset" or "no-reset"?
     2. Should we just keep the existing protected sources implementation
        in place?

For (1), I am fine with either.  For (2), I still think that we can make 
"pic-no-reset" a synonym for "protected-sources" and that things will 
work out.

 From the feedback I have received so far, the fundamental ideas in this 
patch set are sane.  However, the following issues still need agreement:

     1. What should be the name of the no reset property?
        "pic-no-reset" or "no-reset"?
     2. Should we just keep the existing protected sources implementation
        in place?

For (1), I prefer "no-reset".  For (2), I still think that we can make 
"no-reset" a synonym for "protected-sources" and that things will work out.

Ben, you said that you would really like to leave the protected sources 
implementation alone.  Is the mechanism implemented in "PATCH v3 3/4" 
[1] of having "protected-sources" as a synonym for "pic-no-reset" not 
suitable?
