* 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.
|
|
|
|
Required properties:
|
|
- compatible : Should be:
|
|
- "ti,omap4460-control-bandgap" : for OMAP4460 bandgap
|
|
- "ti,omap5430-control-bandgap" : for OMAP5430 bandgap
|
|
- interrupts : this entry should indicate which interrupt line
|
|
the talert signal is routed to;
|
|
Specific:
|
|
- ti,tshut-gpio : this entry should be used to inform which GPIO
|
|
line the tshut signal is routed to;
|
|
|
|
Example:
|
|
|
|
bandgap {
|
|
reg = <0x4a002260 0x4
|
|
0x4a00232C 0x4
|
|
0x4a002378 0x18>;
|
|
compatible = "ti,omap4460-control-bandgap";
|
|
interrupts = <0 126 4>; /* talert */
|
|
ti,tshut-gpio = <86>;
|
|
};
