Thermal driver on i.MX8M SoCs

[philippe_schenk]

Hello

In the Linux Reference Manual (https://www.nxp.com/docs/en/reference-manual/IMX_REFERENCE_MANUAL.pdf) it states on chapter 2.9.1 that the driver CONFIG_IMX8M_THERMAL should be enabled to make use of that thermal driver features.

However I noticed the respective file on 5.4 kernel now gets compiled with CONFIG_QORIQ_THERMAL.

1. Is this information in the Reference Manual maybe wrong or not complete?
2. Does the thermal driver CONFIG_QORIQ_THERMAL still work for i.MX8M Mini SoC on 5.4.24_2.1.0​​ release?

Best Regards,

Philippe

Hello philippe_schenk,

it's driver name is imx8mq-tmu,  it's driver source code is ./thermal/qoriq_thermal.c,  so you are right.

CONFIG_QORIQ_THERMAL should be selected. Below is from Makefile:

----

-$(CONFIG_QORIQ_THERMAL) += qoriq_thermal.o

----

>>Does the thermal driver CONFIG_QORIQ_THERMAL still work for i.MX8M Mini SoC on 5.4.24_2.1.0​​ release?

No, it doesn't.

drivers/thermal/imx8mm_thermal.c is for i.MX8M Mini SoC ,

......

obj-$(CONFIG_IMX8MM_THERMAL) += imx8mm_thermal.o

......

Hope this information is helpful to you.

Have a nice day!

B.R,
