Cover letter [PATCH V9 0/3] soc: imx: add scu firmware api support
Quoted 14 lines · Dong Aisheng
Unlike the former i.MX Architectures, the new generation i.MX8 SoCs (e.g. MX8QXP and MX8QM) contain a system controller which runs on a dedicated Cortex-M core to provide power, clock, Pad, and resource management. Communication between the host processor running an OS and the system controller happens through a SCU protocol. This patchset adds the SCU APIs which is implemented based on MU and will be used by different system components.
It mainly consists of below parts:
1) SCU IPC
Basic IPC mechanism implemention based on mailbox which is used for communication between AP and SCU firmware.
2) SCU IPC Service API
