`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.

`reg`	`array`	Channel identifier. This property is required. See Important properties for more information.
`zephyr,gain`	`string`	Gain selection: - ADC_GAIN_1_6: x 1/6 - ADC_GAIN_1_5: x 1/5 - ADC_GAIN_1_4: x 1/4 - ADC_GAIN_1_3: x 1/3 - ADC_GAIN_2_5: x 2/5 - ADC_GAIN_1_2: x 1/2 - ADC_GAIN_2_3: x 2/3 - ADC_GAIN_4_5: x 4/5 - ADC_GAIN_1: x 1 - ADC_GAIN_2: x 2 - ADC_GAIN_3: x 3 - ADC_GAIN_4: x 4 - ADC_GAIN_6: x 6 - ADC_GAIN_8: x 8 - ADC_GAIN_12: x 12 - ADC_GAIN_16: x 16 - ADC_GAIN_24: x 24 - ADC_GAIN_32: x 32 - ADC_GAIN_64: x 64 - ADC_GAIN_128: x 128 This property is required. Legal values: `'ADC_GAIN_1_6'`, `'ADC_GAIN_1_5'`, `'ADC_GAIN_1_4'`, `'ADC_GAIN_1_3'`, `'ADC_GAIN_2_5'`, `'ADC_GAIN_1_2'`, `'ADC_GAIN_2_3'`, `'ADC_GAIN_4_5'`, `'ADC_GAIN_1'`, `'ADC_GAIN_2'`, `'ADC_GAIN_3'`, `'ADC_GAIN_4'`, `'ADC_GAIN_6'`, `'ADC_GAIN_8'`, `'ADC_GAIN_12'`, `'ADC_GAIN_16'`, `'ADC_GAIN_24'`, `'ADC_GAIN_32'`, `'ADC_GAIN_64'`, `'ADC_GAIN_128'`
`zephyr,reference`	`string`	Reference selection: - ADC_REF_VDD_1: VDD - ADC_REF_VDD_1_2: VDD/2 - ADC_REF_VDD_1_3: VDD/3 - ADC_REF_VDD_1_4: VDD/4 - ADC_REF_INTERNAL: Internal - ADC_REF_EXTERNAL0: External, input 0 - ADC_REF_EXTERNAL1: External, input 1 This property is required. Legal values: `'ADC_REF_VDD_1'`, `'ADC_REF_VDD_1_2'`, `'ADC_REF_VDD_1_3'`, `'ADC_REF_VDD_1_4'`, `'ADC_REF_INTERNAL'`, `'ADC_REF_EXTERNAL0'`, `'ADC_REF_EXTERNAL1'`
`zephyr,vref-mv`	`int`	This property can be used to specify the voltage (in millivolts) of the reference selected for this channel, so that applications can get that value if needed for some calculations. For the internal reference, the voltage can be usually obtained with a dedicated ADC API call, so there is no need to use this property in that case, but for other references this property can be useful.
`zephyr,acquisition-time`	`int`	Acquisition time. Use the ADC_ACQ_TIME macro to compose the value for this property or pass ADC_ACQ_TIME_DEFAULT to use the default setting for a given hardware (e.g. when the hardware does not allow to configure the acquisition time). This property is required.
`zephyr,differential`	`boolean`	When set, selects differential input mode for the channel. Otherwise, single-ended mode is used unless the zephyr,input-negative property is specified, in which case the differential mode is selected implicitly.
`zephyr,input-positive`	`int`	Positive ADC input. Used only for drivers that select the ADC_CONFIGURABLE_INPUTS Kconfig option.
`zephyr,input-negative`	`int`	Negative ADC input. Used only for drivers that select the ADC_CONFIGURABLE_INPUTS Kconfig option. When specified, implies the differential input mode for the channel.
`zephyr,resolution`	`int`	ADC resolution to be used for the channel.
`zephyr,oversampling`	`int`	Oversampling setting to be used for the channel. When specified, each sample is averaged from 2^N conversion results (where N is the provided value).
`zephyr,current-source-pin`	`uint8-array`	Output pin selection for the current sources. The actual interpretation depends on the driver. This is used only for drivers which select the ADC_CONFIGURABLE_EXCITATION_CURRENT_SOURCE_PIN Kconfig option.
`zephyr,vbias-pins`	`int`	Output pin selection for the bias voltage. The actual interpretation depends on the driver. This is used only for drivers which select the ADC_CONFIGURABLE_VBIAS_PIN Kconfig option.
