Hello, I'm trying to use the PN7120 through the device tree but there is a confusion between what the app note ( https://www.nxp.com/docs/en/application-note/AN11697.pdf ) says and the device tree binding: The device tree binding ( https://elixir.bootlin.com/linux/latest/source/Documentation/devicetree/bindings/net/nfc/nxp-nci.txt ) says that the device tree should be implemented this way :
&i2c2 { npc100: npc100@29
{
compatible = "nxp,nxp-nci-i2c";
reg = <0x29>; clock-frequency = <100000>;
interrupt-parent = <&gpio1>;
interrupts = <29 IRQ_TYPE_LEVEL_HIGH>;
enable-gpios = <&gpio0 30 GPIO_ACTIVE_HIGH>;
firmware-gpios = <&gpio0 31 GPIO_ACTIVE_HIGH>;
};
};
The app note says: &i2c{ status = "okay"; pn547: pn547@28 {
compatible = "nxp,pn547";
reg = <0x28>;
clock-frequency = <400000>;
interrupt-gpios = <&gpio2 17 0>;
enable-gpios = <&gpio4 21 0>;
};
};
could someone tell me what's the correct implementation?
I already submitted a ticket to NXP but apparently they're not interested with that kind of issue
