4 Sources of IIO channels can be represented by any node in the device
5 tree. Those nodes are designated as IIO providers. IIO consumer
6 nodes use a phandle and IIO specifier pair to connect IIO provider
7 outputs to IIO inputs. Similar to the gpio specifiers, an IIO
8 specifier is an array of one or more cells identifying the IIO
9 output on a device. The length of an IIO specifier is defined by the
10 value of a #io-channel-cells property in the IIO provider node.
