Merge tag 'cpuidle_psci-v5.5-rc4' of git://git.linaro.org/people/ulf.hansson/linux-pm into arm/drivers
Initial support for hierarchical CPU arrangement, managed by PSCI and its corresponding cpuidle driver. This support is based upon using the generic PM domain, which already supports devices belonging to CPUs. Finally, these is a DTS patch that enables the hierarchical topology to be used for the Qcom 410c Dragonboard, which supports the PSCI OS-initiated mode. * tag 'cpuidle_psci-v5.5-rc4' of git://git.linaro.org/people/ulf.hansson/linux-pm: (611 commits) arm64: dts: Convert to the hierarchical CPU topology layout for MSM8916 cpuidle: psci: Add support for PM domains by using genpd PM / Domains: Introduce a genpd OF helper that removes a subdomain cpuidle: psci: Support CPU hotplug for the hierarchical model cpuidle: psci: Manage runtime PM in the idle path cpuidle: psci: Prepare to use OS initiated suspend mode via PM domains cpuidle: psci: Attach CPU devices to their PM domains cpuidle: psci: Add a helper to attach a CPU to its PM domain cpuidle: psci: Support hierarchical CPU idle states cpuidle: psci: Simplify OF parsing of CPU idle state nodes cpuidle: dt: Support hierarchical CPU idle states of: base: Add of_get_cpu_state_node() to get idle states for a CPU node firmware: psci: Export functions to manage the OSI mode dt: psci: Update DT bindings to support hierarchical PSCI states cpuidle: psci: Align psci_power_state count with idle state count Linux 5.5-rc4 locks: print unsigned ino in /proc/locks riscv: export flush_icache_all to modules riscv: reject invalid syscalls below -1 riscv: fix compile failure with EXPORT_SYMBOL() & !MMU ...
