This however caused regression for n900 display power that needed the PMIC configuration to be disabled with commit d937678ab625 (ARM: dts: Revert enabling of twl configuration for n900). Turns out the root cause of the problem is that we must use TWL4030_RESCONFIG_UNDEF instead of DEV_GRP_NULL to avoid disabling regulators that may have been enabled before the init function for twl4030-power.c runs. With TWL4030_RESCONFIG_UNDEF we let the regulator framework control the regulators like it should. Here we need to only configure the sys_clken and sys_off_mode triggers for the regulators that cannot be done by the regulator framework as it's not running at that point. This allows us to enable the PMIC configuration for n900.
