  To: linux-iio, devicetree; +Cc: robh+dt, Alexandru Ardelean

The ADX345 supports both I2C & SPI bindings.
This change switches from old text bindings, to YAML bindings, and also
tries to make use of the recent multiple-examples support.

-Required properties:
- - compatible : should be one of
-		"adi,adxl345"
-		"adi,adxl375"
- - reg : the I2C address or SPI chip select number of the sensor
-
-Required properties for SPI bus usage:
- - spi-max-frequency : set maximum clock frequency, must be 5000000
- - spi-cpol and spi-cpha : must be defined for adxl345 to enable SPI mode 3
-
-Optional properties:
- - interrupts: interrupt mapping for IRQ as documented in
-   Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
-
-Example for a I2C device node:
