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@xxxxxxxxxx/ 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@xxxxxxxxxx/ 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 Tudor Ambarus (3): dt-bindings: firmware: add samsung,exynos-acpm-ipc bindings firmware: add exynos ACPM protocol driver MAINTAINERS: add entry for the samsung exynos ACPM mailbox protocol .../firmware/samsung,exynos-acpm-ipc.yaml | 64 ++ MAINTAINERS | 10 + drivers/firmware/Kconfig | 1 + drivers/firmware/Makefile | 1 + drivers/firmware/samsung/Kconfig | 14 + drivers/firmware/samsung/Makefile | 4 + drivers/firmware/samsung/exynos-acpm-pmic.c | 226 +++++ drivers/firmware/samsung/exynos-acpm-pmic.h | 24 + drivers/firmware/samsung/exynos-acpm.c | 772 ++++++++++++++++++ drivers/firmware/samsung/exynos-acpm.h | 15 + .../linux/soc/samsung/exynos-acpm-protocol.h | 57 ++ 11 files changed, 1188 insertions(+) create mode 100644 Documentation/devicetree/bindings/firmware/samsung,exynos-acpm-ipc.yaml create mode 100644 drivers/firmware/samsung/Kconfig create mode 100644 drivers/firmware/samsung/Makefile create mode 100644 drivers/firmware/samsung/exynos-acpm-pmic.c create mode 100644 drivers/firmware/samsung/exynos-acpm-pmic.h create mode 100644 drivers/firmware/samsung/exynos-acpm.c create mode 100644 drivers/firmware/samsung/exynos-acpm.h create mode 100644 include/linux/soc/samsung/exynos-acpm-protocol.h -- 2.47.0.338.g60cca15819-goog
