i.MX8M mini TMU SW calibration code

Hello, Is imx8mm_thermal.c the code to perform SW calibration? Current version is "imx_5.4.70_2.3.0", but are there any plans to update it for TMU SW calibration?

@Tori-san
Hello,

Generally the calibration points are measured during the manufacturing testing,
and are programmed in the fuse registers - no need for customers to implement
the calibration.

Regards,
Yuri.

Hi Yuri, Thank you for your reply. I interpret that I don't need to calibrate with the default setting. However, if more accurate calibration is required, it should be implemented in the driver(imx8mm_thermal.c) using the equation desribed in RM. Best regards, Tori-san.
