> NXP i.MX8QXP is an ARMv8 SoC with a Cortex-M4 core inside as system
> controller, the system controller is in charge of system power, clock and
> thermal sensors etc. management, Linux kernel has to communicate with
> system controller via MU (message unit) IPC to get temperature from thermal
> sensors, this patch adds binding doc for i.MX system controller thermal
> driver.
