Question:  has anyone figured out how to set the I2C bus speed without 
disabling cape-universal?    I'd like to increase the bus speed from 100khz 
to 400, but every attempt I make using overlays from uEnv.txt seems to also 
disable cape-universal which I also need.   Do I need to explicitly  add 
the appropriate cape-universal overlay to the list of overlays?     It seem 
like if I do:

uboot_overlay_addr4=/lib/firmware/cape-universalh-00A0.dtbo
uboot_overlay_addr5=/lib/firmware/BB-I2C2-FAST-FPP-00A0.dtbo

then the universal stuff works, but is that really what I'm supposed to 
do?    Seems a bit more error prone as the disable_uboot_overlay_* stuff 
doesn't seem to come into play and I need to grab the appropriate 
cape-universal* file manually.   

Thanks!
Dan
