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>,
	}
