In preparation for adding the power tree for this board, add a node for
the MT6360 PMIC, connected to I2C6.

Why do you add new device in pieces? Logical change is "new device", not
"half of device". If the patch is too big, sure, split it into two
chunks, but not 15!

Best regards,
Krzysztof

Well we have done that in the past, so somehow for MediaTek tree that's ok to 
do. From my personal maintainer position it's easier to review 15 small patches 
then one or two huge ones.
