description: |
QPNP PMIC current ADC (IADC) provides interface to clients to read current.
A 16 bit ADC is used for current measurements. IADC can measure the current
through an external resistor (channel 1) or internal (built-in) resistor
(channel 0). When using an external resistor it is to be described by
qcom,external-resistor-micro-ohms property.
properties:
compatible:
const: qcom,spmi-iadc
reg:

maxItems: 1
qcom,external-resistor-micro-ohms:
description:
Sensor resistor value. If not defined value of 10000 micro Ohms
will be used.
interrupts:
maxItems: 1
description:
End of conversion interrupt.
