Merge tag 'dtpm-v5.16' of https://git.linaro.org/people/daniel.lezcano/linux
Pull Dynamic Thermal Power Management (DTPM) framework changes for v5.16 from Daniel Lezcano: - Simplify and make the code more self-encapsulate by dealing with the dtpm structure only (Daniel Lezcano) - Fix power intialization (Daniel Lezcano) - Add the CPU load consideration when estimating the instaneous power consumption (Daniel Lezcano) * tag 'dtpm-v5.16' of https://git.linaro.org/people/daniel.lezcano/linux: powercap/drivers/dtpm: Fix power limit initialization powercap/drivers/dtpm: Scale the power with the load powercap/drivers/dtpm: Use container_of instead of a private data field powercap/drivers/dtpm: Simplify the dtpm table powercap/drivers/dtpm: Encapsulate even more the code
