STM32MP1 internal temp sensor support removed from latest kernels?

[Grodriguez]

Previous kernel versions had support for the STM32MP1 internal temp sensor. See:

• stm32mp1-adc-temp definition in stm32mp157c device tree
• DT bindings documentation

Apparently this has been removed in later kernels. Isn't this supported anymore ?

Thanks,

Guillermo

Hi Grodriguez (Community Member),

The ADC temp sensor support has been removed from OpenSTLinux versions > 1.2.0, however you can use instead the Digital temperature sensor which is much more accurate.
