MIPS_CPS_CPUIDLE

CPU Idle driver for MIPS CPS platforms

Select this option to enable processor idle state management
through cpuidle for systems built around the MIPS Coherent
Processing System (CPS) architecture. In order to make use of
the deepest idle states you will need to ensure that you are
also using the CONFIG_MIPS_CPS SMP implementation.
