1* Texas Instrument OMAP SCM bandgap bindings

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,omap4460-control-bandgap" : for OMAP4460 bandgap
14  - "ti,omap5430-control-bandgap" : for OMAP5430 bandgap
15- interrupts : this entry should indicate which interrupt line
16the talert signal is routed to;
17Specific:
18- ti,tshut-gpio : this entry should be used to inform which GPIO
19line the tshut signal is routed to;

21Example:
22
23bandgap {
24    reg = <0x4a002260 0x4
25        0x4a00232C 0x4
26        0x4a002378 0x18>;
27    compatible = "ti,omap4460-control-bandgap";
28    interrupts = <0 126 4>; /* talert */
29    ti,tshut-gpio = <86>;
