1	* Texas Instrument OMAP SCM bandgap bindings
2	
3	In the System Control Module, OMAP supplies a voltage reference
4	and a temperature sensor feature that are gathered in the band
5	gap voltage and temperature sensor (VBGAPTS) module. The band
6	gap provides current and voltage reference for its internal
7	circuits and other analog IP blocks. The analog-to-digital
8	converter (ADC) produces an output value that is proportional
9	to the silicon temperature.
10	
11	Required 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
20	the talert signal is routed to;
21	Specific:
22	- gpios : this entry should be used to inform which GPIO
23	line the tshut signal is routed to. The informed GPIO will
24	be treated as an IRQ;
25	- regs : this entry must also be specified and it is specific
26	to each bandgap version, because the mapping may change from
27	soc to soc, apart of depending on available features.
