Subject: [PATCH V9 0/3] soc: imx: add scu firmware api support
Date: Sun, 7 Oct 2018 21:04:40 +0800 [thread overview]
Message-ID: <1538917483-1818-1-git-send-email-aisheng.dong@nxp.com> (raw)
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
