| * 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>; |
| }; |
