Yes I should be able to find a device or 2 which poke GPIOs from the
VBT MIPI sequences. Unfortunately I don't know from the top of my head
which devices actually use this, so I may need to try quite a few devices
before finding one which actually uses this.

I'll try to get this series tested sometime the coming weeks,
depending on when I can schedule some time for this.

Regards,

Hans
