I have been thinking about ordering a GTA04A5, but there is one barrier.
I need to be confident that it can draw less than 10mA in standby.
Currently the best we have seen with GTA04A3,4 is about 20mA (and 40mA on
Linux 4.0, but that must be a software issue).

This is probably a software issue, but until it's actually been demonstrated
that the hardware can sit in standby using under 10mA, I cannot be certain.

It's all very frustrating...
