Yamato (Ati) had some hardware assist for binning and Yoda (Qualcomm) takes it further. I don't know how much driver involvement is necessary relative to IMG's designs.
I believe it would be more apt to say Yamato DX had some software assist for binning. And by software I'm referring to 'things not happening onboard the gpu'.
