voltage-divider¶

Vendor: Generic or vendor-independent

Description¶

Description for a voltage divider, with optional ability to measure
resistance of the upper leg.

Properties¶

Properties not inherited from the base binding file.

Name

Type

Details

output-ohms

int

Resistance of the lower leg of the voltage divider

This property is required.

full-ohms

int

Resistance of the full path through the voltage divider.

If absent or zero the driver assumes that the upper leg is a
resistance-based sensor.

power-gpios

phandle-array

Control power to the voltage divider inputs.

If present the corresponding GPIO must be set to an active level
to enable the divider input.

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “voltage-divider” compatible.

Name	Type	Details
`io-channels`	`phandle-array`	Channels available with this divider configuration. This property is required.
`status`	`string`	indicates the operational status of a device Legal values: `'ok'`, `'okay'`, `'disabled'`, `'reserved'`, `'fail'`, `'fail-sss'` See Important properties for more information.
`compatible`	`string-array`	compatible strings This property is required. See Important properties for more information.
`reg`	`array`	register space See Important properties for more information.
`reg-names`	`string-array`	name of each register space
`interrupts`	`array`	interrupts for device See Important properties for more information.
`interrupts-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) See Important properties for more information.
`clocks`	`phandle-array`	Clock gate information
`clock-names`	`string-array`	name of each clock
`#address-cells`	`int`	number of address cells in reg property
`#size-cells`	`int`	number of size cells in reg property
`dmas`	`phandle-array`	DMA channels specifiers
`dma-names`	`string-array`	Provided names of DMA channel specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
`wakeup-source`	`boolean`	Property to identify that a device can be used as wake up source. When this property is provided a specific flag is set into the device that tells the system that the device is capable of wake up the system. Wake up capable devices are disabled (interruptions will not wake up the system) by default but they can be enabled at runtime if necessary.
