How to add customize compatible properties

[David Duan]

HI  Devzone

i am using <NCS_SOURCE_FOLDER>\nrf\samples\nfc\tag_reader\ to do the test. on NCS1.5.1

i am trying to add a customize compatible properties in device tree. 

&spi0 {
	compatible = "nordic,nrf-spi";
	status = "okay";
	sck-pin = <23>;
	mosi-pin = <21>;
	miso-pin = <22>;
	cs-gpios = <&gpio0 20 GPIO_ACTIVE_LOW>;

	st25r3911b@0 {
		label = "ST25R3911B";
		#compatible = "st,st25r3911b";
		compatible = "david,david_test;
		reg = <0>;
		spi-max-frequency = <4000000>;
		irq-gpios = <&gpio0 3 0>;
		led-nfca-gpios = <&gpio0 29 0>;
	};
};

&spi1 {
	status = "disabled";
};

&spi2 {
	status = "disabled";
};

&spi3 {
	status = "disabled";
};

and i am following the guide https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.6.0/zephyr/guides/dts/bindings.html to add the binding file 

path: <NCS_SOURCE_FOLDER>\nrf\dts\bindings\net\nfc\

my binding file is directly copyed from st,st25r3911b.yaml.

the detail could be show as below

compatible: "david,david_test"

include: spi-device.yaml

properties:
    irq-gpios:
      type: phandle-array
      required: true

    led-nfca-gpios:
      type: phandle-array
      required: false

    led-nfcb-gpios:
      type: phandle-array
      required: false

    led-nfcf-gpios:
      type: phandle-array
      required: false

 

Then after compiler, it always report below error:

Qustion: May i know how to add  customize compatible properties ?

Hi,

Comments in .dts files should be C style (/* */ or //, not #).

And, you are missing a " in your 'compatible' field.

Best regards,
