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. + +Required properties: +- compatible : Should be: + - "ti,omap4430-bandgap" : for OMAP4430 bandgap + - "ti,omap4460-bandgap" : for OMAP4460 bandgap + - "ti,omap4470-bandgap" : for OMAP4470 bandgap + - "ti,omap5430-bandgap" : for OMAP5430 bandgap +- interrupts : this entry should indicate which interrupt line +the talert signal is routed to; +Specific: +- gpios : this entry should be used to inform which GPIO +line the tshut signal is routed to.
