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.
