New revision of the power sequences, taking as usual the feedback that was kindly provided about the last version. 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! Changes since v5: * Removed pointers to platform data from resource structure for better code clarity * devm_power_seq_set_build() now automatically checks the DT if no platform data is present, making it possible to remove the explicit DT parsing function * Lots of fixes in the documentation which should be clearer now (thanks Stephen!)
