Hi, I am looking at adding PM support for AM335x based on l-o/master. arch/arm/mach-omap2/pm.c has the following comment: /* * In the case of DT, the PMIC and SR initialization will be done using * a completely different mechanism. * Disable this part if a DT blob is available. */ if (of_have_populated_dt()) return 0; Basic DT support for AM335x is already in mainline so this check causes various PM related inits and also the registration of the suspend ops to be skipped. I tried searching the list archives for any discussion on this but could not find anything. Can someone shed some light on the how the device tree is to be used for PMIC and SR initialization. Any objections to moving the suspend ops registration before the DT blob check?
