1* Texas Instrument dra7xx SCM bandgap bindings 2 3In the System Control Module, SoC 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. 10 11Required properties: 12- compatible : Should be: 13 - "ti,dra752-bandgap" 14- interrupts : this entry should indicate which interrupt line 15the talert signal is routed to; 16- regs : this is specific to each bandgap version, because 17the mapping may change from soc to soc, apart from depending 18on available features. 19 20Optional: 21- gpios : this entry should be used to inform which GPIO 22line the tshut signal is routed to. The informed GPIO will 23be treated as an IRQ; 24 25Example: 26bandgap { 27 reg = <0x4a0021e0 0xc 28 0x4a00232c 0xc 29 0x4a002380 0x2c 30 0x4a0023C0 0x3c 31 0x4a002564 0x8 32 0x4a002574 0x50>; 33 compatible = "ti,dra752-bandgap"; 34 interrupts = <0 126 4>; /* talert */ 35}; 36
