Hi Andrew,

I notice Pin H6 is in your list assigned as a gpio-hog.   This is a
pin I use for the voltage direction control via the translator for
openFSI.  Not familiar with the history here but is that pin being
used for other purposes or is required to be flagged as a gpio-hog?
Currently I'm attempting to grab a descriptor for this without that
requirement.

Thanks,
Chris
