Required properties:

- compatible : Should be:

  - "ti,omap4460-control-bandgap" : for OMAP4460 bandgap

  - "ti,omap5430-control-bandgap" : for OMAP5430 bandgap

  - "ti,omap4430-bandgap" : for OMAP4430 bandgap

  - "ti,omap4460-bandgap" : for OMAP4460 bandgap

  - "ti,omap4470-bandgap" : for OMAP4470 bandgap

  - "ti,omap5430-bandgap" : for OMAP5430 bandgap

- interrupts : this entry should indicate which interrupt line

the talert signal is routed to;

Specific:

- ti,tshut-gpio : this entry should be used to inform which GPIO

line the tshut signal is routed to;

- regs : this entry must also be specified and it is specific

to each bandgap version, because the mapping may change from

soc to soc, apart of depending on available features.



Example:

OMAP4430:

bandgap {

	reg = <0x4a002260 0x4 0x4a00232C 0x4>;

	compatible = "ti,omap4430-bandgap";

};



OMAP4460:

bandgap {

	reg = <0x4a002260 0x4

		0x4a00232C 0x4

		0x4a002378 0x18>;

	compatible = "ti,omap4460-bandgap";

	interrupts = <0 126 4>; /* talert */

	ti,tshut-gpio = <86>;

};



OMAP4470:

bandgap {

	reg = <0x4a002260 0x4

		0x4a00232C 0x4

		0x4a002378 0x18>;

	compatible = "ti,omap4460-control-bandgap";

	compatible = "ti,omap4470-bandgap";

	interrupts = <0 126 4>; /* talert */

	ti,tshut-gpio = <86>;
