[V9,0/3] soc: imx: add scu firmware api support

Message

Dong Aisheng Oct. 7, 2018, 1:04 p.m. UTC

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

v8->v9:
 * only scu headfile path update from include/soc/imx to
   include/linux/firmware/imx

  firmware: imx: add SCU firmware driver support
  firmware: imx: add misc svc support

Applied all, thanks.

I'm waiting for the MAINTAINERS update to send another pull request to
arm-soc folks.
