+/**
+ * DOC: Coupled cpuidle states
+ *
+ * On some ARM SMP SoCs (OMAP4460, Tegra 2, and probably more), the
+ * cpus cannot be independently powered down, either due to
+ * sequencing restrictions (on Tegra 2, cpu 0 must be the last to
+ * power down), or due to HW bugs (on OMAP4460, a cpu powering up
+ * will corrupt the gic state unless the other cpu runs a work
+ * around). Each cpu has a power state that it can enter without
+ * coordinating with the other cpu (usually Wait For Interrupt, or
+ * WFI), and one or more "coupled" power states that affect blocks
+ * shared between the cpus (L2 cache, interrupt controller, and
+ * sometimes the whole SoC). Entering a coupled power state must
+ * be tightly controlled on both cpus.
+ *
+ * This file implements a solution, where each cpu will wait in the
+ * WFI state until all cpus are ready to enter a coupled state, at
+ * which point the coupled state function will be called on all
+ * cpus at approximately the same time.
+ *
+ * Once all cpus are ready to enter idle, they are woken by an smp
+ * cross call. At this point, there is a chance that one of the
+ * cpus will find work to do, and choose not to enter idle. A
+ * final pass is needed to guarantee that all cpus will call the
+ * power state enter function at the same time. During this pass,
+ * each cpu will increment the ready counter, and continue once the
+ * ready counter matches the number of online coupled cpus. If any
+ * cpu exits idle, the other cpus will decrement their counter and
+ * retry.
+ *
+ * requested_state stores the deepest coupled idle state each cpu
+ * is ready for. It is assumed that the states are indexed from
+ * shallowest (highest power, lowest exit latency) to deepest
+ * (lowest power, highest exit latency). The requested_state
+ * variable is not locked. It is only written from the cpu that
+ * it stores (or by the on/offlining cpu if that cpu is offline),
+ * and only read after all the cpus are ready for the coupled idle
+ * state are are no longer updating it.
+ *
+ * Three atomic counters are used. alive_count tracks the number
+ * of cpus in the coupled set that are currently or soon will be
+ * online. waiting_count tracks the number of cpus that are in
+ * the waiting loop, in the ready loop, or in the coupled idle state.
+ * ready_count tracks the number of cpus that are in the ready loop
+ * or in the coupled idle state.
+ *
+ * To use coupled cpuidle states, a cpuidle driver must:
+ *
+ * Set struct cpuidle_device.coupled_cpus to the mask of all
+ * coupled cpus, usually the same as cpu_possible_mask if all cpus
+ * are part of the same cluster. The coupled_cpus mask must be
+ * set in the struct cpuidle_device for each cpu.
+ *
+ * Set struct cpuidle_device.safe_state to a state that is not a
+ * coupled state. This is usually WFI.
+ *
+ * Set CPUIDLE_FLAG_COUPLED in struct cpuidle_state.flags for each
+ * state that affects multiple cpus.
+ *
+ * Provide a struct cpuidle_state.enter function for each state
+ * that affects multiple cpus. This function is guaranteed to be
+ * called on all cpus at approximately the same time. The driver
+ * should ensure that the cpus all abort together if any cpu tries
+ * to abort once the function is called. The function should return
+ * with interrupts still disabled.
