   1 * Texas Instrument OMAP SCM bandgap bindings
   2
   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.

  11 Required properties:
  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;
  19 Specific:
  20 - ti,tshut-gpio : this entry should be used to inform which GPIO
  21 line the tshut signal is routed to;
  22 - regs : this entry must also be specified and it is specific
  23 to each bandgap version, because the mapping may change from
  24 soc to soc, apart of depending on available features.

  26 Example:
  27 OMAP4430:
  28 bandgap {
  29         reg = <0x4a002260 0x4 0x4a00232C 0x4>;
  30         compatible = "ti,omap4430-bandgap";
  31 };
  32
  33 OMAP4460:
  34 bandgap {
  35         reg = <0x4a002260 0x4
  36                 0x4a00232C 0x4
  37                 0x4a002378 0x18>;
  38         compatible = "ti,omap4460-bandgap";
  39         interrupts = <0 126 4>; /* talert */
  40         ti,tshut-gpio = <86>;
  41 };
  42
  43 OMAP4470:

  45         reg = <0x4a002260 0x4
  46                 0x4a00232C 0x4
  47                 0x4a002378 0x18>;
  48         compatible = "ti,omap4470-bandgap";
  49         interrupts = <0 126 4>; /* talert */
  50         ti,tshut-gpio = <86>;
  51 };

  53 OMAP5430:
  54 bandgap {
  55         reg = <0x4a0021e0 0xc
  56                 0x4a00232c 0xc
  57                 0x4a002380 0x2c
