What is making DSS powerdomain switch back and forth? I can see the above also after I've loaded and then unloaded the DSS modules. There seems to be usecount of one for dss_pwrdm (pm_debug/count shows dss_clkdm->dss_pwrdm (1)) and usecount of 4 for dss_ick. Any ideas? I remember somebody (Benoit?) saying that the hwmod/omap_device code keeps ick allocated, but even so I'd presume that DSS stays in RET is it's not used. Tomi
