Kernel-4.18.0-80.el8_s3fwrn5

• Samsung S3FWRN5 NCI NFC Controller

Required properties:

• compatible: Should be “samsung,s3fwrn5-i2c”.
• reg: address on the bus
• interrupt-parent: phandle for the interrupt gpio controller
• interrupts: GPIO interrupt to which the chip is connected
• s3fwrn5,en-gpios: Output GPIO pin used for enabling/disabling the chip
• s3fwrn5,fw-gpios: Output GPIO pin used to enter firmware mode and
  sleep/wakeup control

Example:

&hsi2c_4 {
s3fwrn5@27 {
compatible = “samsung,s3fwrn5-i2c”;

    reg = <0x27>;

    interrupt-parent = <&gpa1>;
    interrupts = <3 0 0>;

    s3fwrn5,en-gpios = <&gpf1 4 0>;
    s3fwrn5,fw-gpios = <&gpj0 2 0>;
};

};
