Hi Nate,

For your future reference, patches that look at the device tree should
also cc: devicetree-discuss-uLR06cmDAlY/bJ5BZ2RsiQ@public.gmane.org so that new bindings can
be reviewed and common mistakes can be avoided.  It is expected that
new device tree bindings are accompanied with documentation describing
what the binding is for and how it should be used (see
Documentation/powerpc/dts-bindings).

I know this change is already in mainline, but can you please post the
device tree fragment that you're using to describe this chip?  I want
to make sure we don't get stuck with things in the kernel that will be
hard to maintain in the long term.

Thanks,
g.
