Merge branch 'pm-cpuidle'
Merge cpuidle updates for 6.16-rc1: - Optimize bucket assignment when next_timer_ns equals KTIME_MAX in the menu cpuidle governor (Zhongqiu Han). - Convert the cpuidle PSCI driver to a faux device one (Sudeep Holla). - Add C1 demotion on/off sysfs knob to the intel_idle driver (Artem Bityutskiy). - Fix typos in two comments in the teo cpuidle governor (Atul Kumar Pant). * pm-cpuidle: cpuidle: psci: Avoid initializing faux device if no DT idle states are present Documentation: ABI: testing: document the new cpuidle sysfs file Documentation: admin-guide: pm: Document intel_idle C1 demotion intel_idle: Add C1 demotion on/off sysfs knob cpuidle: psci: Transition to the faux device interface cpuidle: menu: Optimize bucket assignment when next_timer_ns equals KTIME_MAX cpuidle: teo: Fix typos in two comments
