The registers for the bt-bmc device live under the Aspeed LPC
controller. Devicetree bindings have recently been introduced for the
LPC controller where the "host" portion of the LPC register space is
described as a syscon device. Future devicetrees describing the bt-bmc
device should nest its node under the appropriate "simple-mfd", "syscon"
compatible node.

This change allows the bt-bmc driver to function with both syscon and
non-syscon- based devicetree descriptions by always using a regmap for
register access, either retrieved from the parent syscon device or
instantiated if none exists.

The patch has been tested on an OpenPOWER Palmetto machine, successfully
booting, rebooting and powering down the host.

It would be nice to have an example of the associated binding.
I did not see it. A part from that :

Will this make it into 4.11?

I thought you were doing a v2 with a few little fixes. Get it to me quickly, if you can.
