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.
