This is the platform function interpreter itself along with the backends for UniN/U3/U4, mac-io, GPIOs and i2c. It adds the ability to execute those do-platform-* scripts in the device-tree (at least for most devices for which a backend is provided). This should replace the clock spreading hacks properly. It might also have an impact on all sort of machines since some of the scripts marked "at init" will now be executed on boot (or some other on sleep/wakeup), those will possibly do things that the kernel didn't do at all, like setting some values into some i2c devices (changing thermal sensor calibration or conversion rate) etc... Thus regression testing is MUCH welcome. Also loook for errors in dmesg. That's also why I've left rather verbose debugging enabled in this version of the patch. (I do expect some Windtunnel G4s to show some errors as they have an i2c clock chip on the PMU bus that uses some primitives that the i2c backend doesn't implement yet. I really need users that have one of those machine to come back to me so we can get that done right, though the errors themselves should be harmless, I suspect the machine might not run at full speed).
