Subject: [PATCH v4 2/4] dt-bindings: iio: magnetometer: Add Voltafield AF8133J
From: Icenowy Zheng <icenowy@...c.io>
Voltafield AF8133J is a simple magnetometer sensor produced by Voltafield
Technology Corp, with dual power supplies (one for core and one for I/O)
and active-low reset pin.
The sensor has configurable range 1.2 - 2.2 mT and a software controlled
standby mode.
Add a device tree binding for it.
