      cpuidle: Invert CPUIDLE_FLAG_TIME_VALID logic · b82b6cca
      Daniel Lezcano authored
      The only place where the time is invalid is when the ACPI_CSTATE_FFH entry
      method is not set. Otherwise for all the drivers, the time can be correctly
      measured.
      
      Instead of duplicating the CPUIDLE_FLAG_TIME_VALID flag in all the drivers
      for all the states, just invert the logic by replacing it by the flag
      CPUIDLE_FLAG_TIME_INVALID, hence we can set this flag only for the acpi idle
      driver, remove the former flag from all the drivers and invert the logic with
      this flag in the different governor.

      cpuidle: cpuidle-cps: add MIPS CPS cpuidle driver · d0508944
      Paul Burton authored
      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.
