By the way, there's still something funny with DSS powerdomain. As I
said in the original post:

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.
