* Texas Instrument OMAP SCM bandgap bindings In the System Control Module, OMAP 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,omap34xx-bandgap" : for OMAP34xx bandgap - "ti,omap36xx-bandgap" : for OMAP36xx 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: - 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; - 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: OMAP34xx: bandgap { reg = <0x48002524 0x4>; compatible = "ti,omap34xx-bandgap"; }; OMAP36xx: bandgap { reg = <0x48002524 0x4>; compatible = "ti,omap36xx-bandgap"; }; 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 */ gpios = <&gpio3 22 0>; /* tshut */ }; OMAP4470: bandgap { reg = <0x4a002260 0x4 0x4a00232C 0x4 0x4a002378 0x18>; compatible = "ti,omap4470-bandgap"; interrupts = <0 126 4>; /* talert */ gpios = <&gpio3 22 0>; /* tshut */ }; OMAP5430: bandgap { reg = <0x4a0021e0 0xc 0x4a00232c 0xc 0x4a002380 0x2c 0x4a0023C0 0x3c>; compatible = "ti,omap5430-bandgap"; interrupts = <0 126 4>; /* talert */ }; DRA752: bandgap { reg = <0x4a0021e0 0xc 0x4a00232c 0xc 0x4a002380 0x2c 0x4a0023C0 0x3c 0x4a002564 0x8 0x4a002574 0x50>; compatible = "ti,dra752-bandgap"; interrupts = <0 126 4>; /* talert */ };
