I thought we went through a lot of different choices when picking this
name, and explicitly did NOT use the "_dma" term here for a reason.  Can
you go and read those old patch submissions to verify why we did so, and
what has changed since then and then document here what has changed to
allow this name change now?

thanks,

Thanks for resending. This probably dropped off my radar since I moved
on to other things. But I can confirm a lot of Chromebooks today in
the market already use this property (and this patchset) for
identifying untrusted DMA capable devices.

Thanks & Best Regards,

Rajat
