Sorry for the resend, I noticed my reply also got horrible mangled.

+Binding for sbs-manager
+
+Required properties:
+- compatible: should be "lltc,ltc1760" or use "sbs,sbs-manager" as fallback.
+- reg: integer, i2c address of the device. Should be <0xa>.
What happened to adding Phil's interrupt support into this? You don't
have to add the whole patch, just the binding part. The driver support
can come later.
Phil revoked his patch. Right now it's not clear how the interrupt/gpio
solution will look like and if they will need an device tree binding at
all...
I'm getting back to this now.
I think we can use the smbalert driver to handle the source interrupt.
Which I think doesn't need anything in the dt binding. Driver just needs to
implement the alert callback.
I haven't figured out if the smb_alert could be used for the sbs-battery
driver interrupt or if this would make sense. However I think it would still need
to be a gpio controller in either case so that it can report the presence of the
batteries in a manner suitable for the sbs-battery driver to use.
I think the gpio controller approach is the simpler method.
It looks like the smbalert_driver driver needs some updates to work with device trees.
I need a bit more time to investigate this option.
