* Texas Instrument OMAP SCM bandgap bindings
In the System Control Module, OMAP supplies a voltage reference
and a temperature sensor feature that are gathered in the band
gap voltage and temperature sensor (VBGAPTS) module. The band
gap provides current and voltage reference for its internal
circuits and other analog IP blocks. The analog-to-digital
converter (ADC) produces an output value that is proportional
to the silicon temperature.

thermal: ti-soc-thermal: use standard GPIO DT bindings This change updates the ti-soc-thermal driver to use standard GPIO DT bindings to read the GPIO number associated to thermal shutdown IRQ, in case the device features it. Previously, the code was using a specific DT bindings. As now OMAP supports the standard way to model GPIOs, there is no point in having a ti specific binding.
