dt-bindings:iio:samsung,sensorhub-rinato: yaml conversion 



Renamed to be more specific as I would be surprised if this is the only
sensorhub Samsung have ever shipped.
Fixed missing reg property in the example

Karol's email address from original patch is bouncing, so I've
put myself as maintainer until someone else steps up.

Samsung Sensorhub driver



Sensorhub is a MCU which manages several sensors and also plays the role

of a virtual sensor device.



Required properties:

- compatible: "samsung,sensorhub-rinato" or "samsung,sensorhub-thermostat"

- spi-max-frequency: max SPI clock frequency

- interrupts: communication interrupt

- ap-mcu-gpios: [out] ap to sensorhub line - used during communication

- mcu-ap-gpios: [in] sensorhub to ap - used during communication

- mcu-reset-gpios: [out] sensorhub reset



Example:



	shub_spi: shub {

		compatible = "samsung,sensorhub-rinato";

		spi-max-frequency = <5000000>;

		interrupt-parent = <&gpx0>;

		interrupts = <2 0>;

		ap-mcu-gpios = <&gpx0 0 0>;

		mcu-ap-gpios = <&gpx0 4 0>;

		mcu-reset-gpios = <&gpx0 5 0>;

	};
