But the commit below[1], added in v3.6 should prevent the any automaic clock gating for devices without drivers bound. Since there is no driver for the OCM RAM block, we are not affected by the automatic idle on suspend anyways. [1]: commit 72bb6f9b51c82c820ddef892455a85b115460904 Author: Kevin Hilman Date: Tue Jul 10 15:29:04 2012 -0700 ARM: OMAP: omap_device: don't attempt late suspend if no driver bound Currently, the omap_device PM domain layer uses the late suspend and early resume callbacks to ensure devices are in their low power states. However, this is attempted even in cases where a driver probe has failed. If a driver's ->probe() method fails, the driver is likely in a state where it is not expecting its runtime PM callbacks to be called, yet currently the omap_device PM domain code attempts to call the drivers callbacks. To fix, use the omap_device driver_status field to check whether a driver is bound to the omap_device before attempting to trigger driver callbacks.
