Hi all, As we're planning to make omap3 device tree only soon, I was poking around and noticed that PM is not working properly. As we're planning to drop about 20k lines of code, I just had to try to fix this so we know what is going on and don't have to go back. I was pretty bummed out to find that we've had non-working PM code in mainline for really long time. Anyways, I got the voltage scaling and N900 debug leds working, so with those we can notice any future regressions immediately :) These are against v3.14, then you might want to also apply the following two patches: [PATCH] of/platform: Fix no irq domain found errors when populating interrupts https://lkml.org/lkml/2014/4/10/620 [PATCH] serial: omap: Fix missing pm_runtime_resume handling by simplifying code http://www.spinics.net/lists/linux-omap/msg104782.html Note that for the actual voltage scaling to happen, the twl4030 PMIC scripts are also needed. I have some uncleaned patches to load those based on the compatible flag, will post those separately. This series alone fixes the idle state signaling to the PMIC, so we can monitor sys_clkreq and sys_off_idle pins properly.
