Subject: [PATCH v2 2/2] devicetree: hwmon: shtc1: Add sensirion,shtc1.yaml

Add documentation for the newly added DTS support in the shtc1 driver.
To align with the drivers logic to have high precision by default
a boolean sensirion,low_precision is used to switch to low precision.

+title: Sensirion SHTC1 Humidity and Temperature Sensor IC
+
+maintainers:
+  - jdelvare@...e.com
+
+description: |
+  The SHTC1, SHTW1 and SHTC3 are digital humidity and temperature sensor
+  designed especially for battery-driven high-volume consumer electronics
+  applications.
+  For further information refere to Documentation/hwmon/shtc1.rst
+
+  This binding document describes the binding for the hardware monitor
+  portion of the driver.
+
+properties:
+  compatible:
+    enum:
+      - sensirion,shtc1
+      - sensirion,shtw1
+      - sensirion,shtc3
+
+  reg: I2C address 0x70
+
+Optional properties:
+  sensirion,blocking_io: |
+    bool, if set the i2c bus hold until measure finished
+  sensirion,low_precision: |
+    bool, if set aquire data with low precision (not recommend)
+
+required:
+  - compatible
+  - reg
+
+additionalProperties: false
+
+Example:
+  &i2c1 {
+    status = "okay";
+    clock-frequency = <400000>;
+
+    shtc3@70 {
+      compatible = "sensirion,shtc3";
+      reg = <0x70>
+      sensirion,blocking_io;
+      status = "okay";
+    };
+  };
