AFAIK it should work fine with the generic "ti,twl4030-power-idle-osc-off".
This means reboot works and regulators are cut off during off mode.

The n900 specific code was based on something before the TI generic values
were available I think. And the last time I looked at it I came to the
conclusion the n900 specific code is no better.

Or did I miss something? Are you seeing some issues with PM with dts based

We can certainly add it to twl4030-power if it provides something that
the "ti,twl4030-power-idle-osc-off" does not.
