Subject: [PATCH 332/389] dt-bindings: iio: magnetometer: add DT binding for
Voltafield AF8133J
Voltafield AF8133J is a quite simple magnetometer produced by Voltafield
Technology Corp, with dual power supplies (one for core and one for IO)
and a active-low reset pin, but without interrupts.
Add a device tree binding for it.
