The mpu clock is stopped for idle states. On GTA04 I experienced also some strange pm issues with omap3isp: rmmod clears up everything fine. After probing, clocks seems to be turned off, but power consumption does not drop. It only drops when there is an iommu_detach paired to that iommu_attach in the driver. But if I add it, the driver does not work properly. Regards, Andreas
