All, The patch set provides DVFS and offmode support for bridgedriver. These patches to be applied on top of the pm branch. Currently Some times we have observed issues like MMU fault and DSP Reset on setting VDD1 to OPP1.
Looks like the drop in voltage to DSP core causing the issue. With a slight increase in VDD1 voltage level for OPP1 [patch 3/3] solving the issue, We are investigating further into this.
