Details are here:

APOs are still tightly bound to hardware. But this allows APO binaries to be 
serviced independently from KSCATEGORY_AUDIO binaries, since they’re in 
different packages.

This driver is a pure APO driver, which targets a software component (SWC) 
exposed by a (different) KSCATEGORY_AUDIO driver.

I didn't think it was possible to do a "pure APO driver".  Have the 
requirements been relaxed?
