+TDK/InvenSense CH101 UltraSonic device
+
+https://invensense.tdk.com/products/ch101/
+
+Required properties:
+ - compatible : should be one of
+		"invensense,ch101"
+ 		"invensense,ch201"
+ - reg : the I2C address of the sensor
+ - rst-gpios: reset pin
+ - rtc_rst-gpios: rtc reset
+ - prg-gpios: program pin.
+ - interrupts: interrupt mapping for IRQ. It should be configured with flags
+   IRQ_TYPE_EDGE_RISING, or IRQ_TYPE_EDGE_FALLING.
+
+  Refer to interrupt-controller/interrupts.txt for generic interrupt client node
+  bindings.
+
+Example:
+
+        ch101_0: ch101_1@45 {
+                compatible = "invensense,ch101";
+                reg = <0x45>;
+                rst-gpios = <&tlmm 140 GPIO_ACTIVE_HIGH>;
+                rtc_rst-gpios = <&tlmm 0 GPIO_ACTIVE_HIGH>;
+                prg-gpios = <0 1 2>;
+                int-gpios = <&tlmm 122 GPIO_ACTIVE_HIGH>,
+                            <&tlmm 123 GPIO_ACTIVE_HIGH>,
