- * Texas Instrument dra7xx SCM bandgap bindings
- In the System Control Module, SoC 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,dra752-bandgap"
- - interrupts : this entry should indicate which interrupt line
- the talert signal is routed to;
- - regs : this is specific to each bandgap version, because
- the mapping may change from soc to soc, apart from depending
- on available features.
- Optional:
- - gpios : this entry should be used to inform which GPIO
- line the tshut signal is routed to. The informed GPIO will
- be treated as an IRQ;
- Example:
- bandgap {
- reg = <0x4a0021e0 0xc
- 0x4a00232c 0xc
- 0x4a002380 0x2c
- 0x4a0023C0 0x3c
- 0x4a002564 0x8
- 0x4a002574 0x50>;
- compatible = "ti,dra752-bandgap";
- interrupts = <0 126 4>; /* talert */
- };
