1 * Texas Instrument OMAP SCM bandgap bindings
3 In the System Control Module, OMAP supplies a voltage reference
4 and a temperature sensor feature that are gathered in the band
5 gap voltage and temperature sensor (VBGAPTS) module. The band
6 gap provides current and voltage reference for its internal
7 circuits and other analog IP blocks. The analog-to-digital
8 converter (ADC) produces an output value that is proportional
9 to the silicon temperature.
12 - compatible : Should be:
13 - "ti,omap4430-bandgap" : for OMAP4430 bandgap
14 - "ti,omap4460-bandgap" : for OMAP4460 bandgap
15 - "ti,omap4470-bandgap" : for OMAP4470 bandgap
16 - "ti,omap5430-bandgap" : for OMAP5430 bandgap
17 - interrupts : this entry should indicate which interrupt line
18 the talert signal is routed to;
20 - gpios : this entry should be used to inform which GPIO
21 line the tshut signal is routed to. The informed GPIO will
23 - regs : this entry must also be specified and it is specific
24 to each bandgap version, because the mapping may change from
25 soc to soc, apart of depending on available features.
