Hi Jassi & Sascha,

Would you help review this new version patch series?

It's changed to generic MU driver using 8 separately MU channels
according to Jassi's suggestion.
Please help check if this is okay to you.

Regards
Dong Aisheng

Subject: [PATCH V5 0/5] soc: imx: add scu firmware api support

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
