This patchset adds support to send certain thermal notifications and facilitate workload throttling in userspace. Userspace apps that want to reduce workload when thermal throttling starts, will have to register for these events and interpret them as per their requirement. This workload throttling allows userspace to react before any hardware clocks are throttled and can keep some critical apps running reliably longer. v3 * Reduced the number of sysfs_notify calls, Notify once per trip only when the temperature crosses the trip point. * Use hysteresis to avoid sending too many notifications when temperatures are bouncing around. * Add trip state tracking. * Add support to disable trip point notifications. v2 * Call sysfs_notify for thermal_zone*/temp only when a trip has violated. v1 * Base version, added two sysfs_notify calls.
