10/15 and 11/15 should be fine to merge already, although 11/15 depends
on the DT bindings in 08/15. Even if the unicam driver needs a respin, I
think the bindings are safe to merge already. Do you plan to take them
in your tree with the corresponding DTS patches ?
For 12/15 (the pinctrl-based I2C multiplexing), I'd really like an ack
from Dave. 13/15 is pretty straightforward but depends on 12/15. 14/15
is independent from all the other patches and can safely be merged I
think.
