New revision of the power sequences, taking as usual the feedback that was

I think now is a good time to discuss integrating this and to start looking for
a maintainer who would be willing to merge this into his/her tree (I am
especially thinking about the power framework maintainers, since this is where
the code is right now. The second patch in this series enables the pwm_backlight
driver to be used with the device tree, without relying on board-dependent
callbacks to support complex power sequences. We also plan to use power
sequences in other Tegra drivers, and other people have expressed interest in
this work during earlier reviews. See for instance

https://lists.ozlabs.org/pipermail/devicetree-discuss/2012-August/018532.html

and

https://lkml.org/lkml/2012/9/6/270

There is probably some more details to fix and improve, but the current shape
should be enough to know if we want this and where - therefore any sign from
a maintainer would be greatly appreciated!

I want to reiterate my opinion that I think power sequences in DT data
is the wrong way to go. Powering sequences are device specific issues
and should be handled in the device driver. But I also think that power
sequences inside the drivers would probably be useful.
