Thanks for that.

My blob uses "yamato_panel.txt" as the config file and understands 
"binning=sw" but not "textureTiling" (and strings doesn't show anything 
similar).

Interestingly, while  using that does make the binning more like the 
freedreno way (there's no longer an initial "binning shader" and there 
is now a DRAW_INDX per tile) the VGT_CURRENT_BIN_ID_MIN/MAX registers 
are still being set and CP_DRAW_INDX_BIN commands are still being issued.

I'll have to do some more digging to see if this is important..
