Subject: [PATCH v3 0/3] firmware: add exynos ACPM protocol driver

Alive Clock and Power Manager (ACPM) Message Protocol is defined for
the purpose of communication between the ACPM firmware and masters
(AP, AOC, ...). ACPM firmware operates on the Active Power Management
(APM) module that handles overall power activities.

This protocol library provides the interface for all the client drivers
making use of the features offered by the APM. Add ACPM protocol support.

I mark this as v3 because it is a continuation of:
https://lore.kernel.org/linux-arm-kernel/20241017163649.3007062-1-tudor.ambarus@linaro.org/

The samsung exynos mailbox controller driver, the transport layer for
ACPM, can be found at:
https://lore.kernel.org/linux-arm-kernel/20241205174137.190545-1-tudor.ambarus@linaro.org/

Changes in v3:
- decouple the mailbox controller driver from the ACPM protocol driver
- address Krzysztof's eview comments 
- add ACPM PMIC protocol helpers

Cheers,
ta
