By "sustainable", do you mean sustainable across Process, Voltage and Temperature corners upto the max rated operational Power-ON hours without IDLE state being achieved on the processor? OR do you mean to leave it up to interpretation? > + > - opp-supported-hw: This property allows a platform to enable only a subset of > the OPPs from the larger set present in the OPP table, based on the current > version of the hardware (already known to the operating system). > -- > 2.17.1 > -- Regards, Nishanth Menon Key (0xDDB5849D1736249D) / Fingerprint: F8A2 8693 54EB 8232 17A3 1A34 DDB5 849D 1736 249D _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
