[PATCH 44/46] dt-bindings:iio:st,st-sensors: txt to yaml conversion.

[Jonathan Cameron <jic23@kernel.org>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

This binding document covers a very large number of different sensors.
As such the existing documentation is less specific than it could
be (such as which devices have 2 interrupt pin options).
That can be improved later.

Denis, are you happy to be listed as maintainer for this one?
If not feel free to suggestion someone else.

-The STMicroelectronics sensor devices are pretty straight-forward I2C or
-SPI devices, all sharing the same device tree descriptions no matter what
-type of sensor it is.
-
-Required properties:
-- compatible: see the list of valid compatible strings below
-- reg: the I2C or SPI address the device will respond to
-
-Optional properties:
-- vdd-supply: an optional regulator that needs to be on to provide VDD
-  power to the sensor.
-- vddio-supply: an optional regulator that needs to be on to provide the
-  VDD IO power to the sensor.
-- st,drdy-int-pin: the pin on the package that will be used to signal
-  "data ready" (valid values: 1 or 2). This property is not configurable
-  on all sensors.
-- drive-open-drain: the interrupt/data ready line will be configured
-  as open drain, which is useful if several sensors share the same
-  interrupt line. (This binding is taken from pinctrl/pinctrl-bindings.txt)
-  This is a boolean property.
-
-Sensors may also have applicable pin control settings, those use the
-standard bindings from pinctrl/pinctrl-bindings.txt.
