2014-05-28cpuidle: cpuidle-cps: add MIPS CPS cpuidle driverPaul Burton1-0/+17
This patch adds a cpuidle driver for systems based around the MIPS Coherent Processing System (CPS) architecture. It supports four idle states: - The standard MIPS wait instruction. - The non-coherent wait, clock gated & power gated states exposed by the recently added pm-cps layer. The pm-cps layer is used to enter all the deep idle states. Since cores in the clock or power gated states cannot service interrupts, the gic_send_ipi_single function is modified to send a power up command for the appropriate core to the CPC in cases where the target CPU has marked itself potentially incoherent.
