Hi, Daniel/Rui/Eduardo Could you please take a look at this patch series? Ansonquoted
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.
