However for mapphone devices Motorola seems to have decided that this does not really matter for the SoC variants they have tested to use, and decided to clock all devices, including the ones with STANDARD performance chips at 1.2GHz upon release of the 3.0.8 vendor kernel shiped with Android 4.0. Therefore it seems safe to do the same, but let's only do it for Motorola devices as the others have not been tested. Note that we prevent overheating with the passive cooling device cpu_alert0 configured in the dts file that starts lowering the speed as needed. This also removes the "failed to find current OPP for freq 1200000000" warning.
