From: Anson Huang <redacted>

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.
