| * 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 */ |
| }; |
