3c9d082064 thermal: stm32: read factory settings inside stm_thermal_prepare
Calling stm_thermal_read_factory_settings before clocking
internal peripheral causes bad register values and makes
temperature computation wrong.

Calling stm_thermal_read_factory_settings inside
stm_thermal_prepare fixes this problem as internal
peripheral is well clocked at this stage.

1d69315560 thermal: add stm32 thermal driver
Add support for DTS thermal sensor that can be
found on some STM32 platforms.

This driver is based on OF and works in interrupt
mode.

It offers two temperature trip points:
passive and critical. The first is intended for
passive cooling notification while the second is
used for over-temperature reset.
