* 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 */
|
||
|
|
};
