1* Texas Instrument OMAP SCM bandgap bindings
2
3In the System Control Module, OMAP supplies a voltage reference
4and a temperature sensor feature that are gathered in the band
5gap voltage and temperature sensor (VBGAPTS) module. The band
6gap provides current and voltage reference for its internal
7circuits and other analog IP blocks. The analog-to-digital
8converter (ADC) produces an output value that is proportional
9to the silicon temperature.

11Required properties:
12- compatible : Should be:
13  - "ti,omap34xx-bandgap" : for OMAP34xx bandgap
14  - "ti,omap36xx-bandgap" : for OMAP36xx bandgap
15  - "ti,omap4430-bandgap" : for OMAP4430 bandgap
16  - "ti,omap4460-bandgap" : for OMAP4460 bandgap
17  - "ti,omap4470-bandgap" : for OMAP4470 bandgap
18  - "ti,omap5430-bandgap" : for OMAP5430 bandgap
19- interrupts : this entry should indicate which interrupt line
20the talert signal is routed to;
21Specific:
22- gpios : this entry should be used to inform which GPIO
23line the tshut signal is routed to. The informed GPIO will
24be treated as an IRQ;
25- regs : this entry must also be specified and it is specific
26to each bandgap version, because the mapping may change from
27soc to soc, apart of depending on available features.
