Subject: [PATCH v4 1/3] dt-bindings: iio: proximity: Add Murata IRS-D200

Murata IRS-D200 is a PIR sensor for human detection. It uses the I2C bus
for communication with interrupt support. Add devicetree bindings
requiring the compatible string, I2C slave address (reg), power supply
and interrupts.
