cpuidle: cpuidle-cps: add MIPS CPS cpuidle driver 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.

MIPS: Kconfig: Add missing MIPS_CPS dependencies to PM and cpuidle The MIPS_CPS_PM and MIPS_CPS_CPUIDLE implementation should depend on the MIPS_CPS symbol to avoid the following build problem arch/mips/kernel/pm-cps.c: In function 'cps_pm_enter_state': arch/mips/kernel/pm-cps.c:164:26: error: 'cpu_coherent_mask' undeclared (first use in this function) cpumask_clear_cpu(cpu, &cpu_coherent_mask); ^ Signed-off-by: Markos Chandras <markos.chandras@imgtec.com> Cc: Paul Burton <paul.burton@imgtec.com> Cc: linux-mips@linux-mips.org Patchwork: http://patchwork.linux-mips.org/patch/7798/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org> 2014-09-18 22:09:49 +07:00			`depends on CPU_IDLE && MIPS_CPS`
