OK. Let me work on this. I tried to capture as much documentation as possible into the series before. One reviewer said I should add it. Another reviewer said I should remove it. Where would be the best place to document the use case? - In the source file? - In the commit message? - In the device-tree documentation? I'll try to write up something based on your and Mark Zyngier's questions for the next release. > > Until that's settled, I don't think this is ready yet, and I don't think > this should be picked up. > > I'm sorry to say that at this stage, as I realise that may sound > obstructive.

I'm going towards V20 with small nitpicks rather than the good feedback like yours. -- Sinan Kaya Qualcomm Technologies, Inc. on behalf of Qualcomm Innovation Center, Inc.
