Re: [PATCH 00/11] NFC: pn533: bug fixes and improvements

[Olliver Schinagl]

Hi Michael,

I know i'm a little late to the party, but why did you not name the 
directory/driver pn53x? I don't think we should debate wether a 533 is a 
532 with a USB added, or wether a 532 is a 533 with the USB stripped, I 
was just curious. As for the pn533-i2c, in the KConfig, I'd probably 
recommend naming it pn532 at the least though, since there is no variant 
other then USB for the 533?

Further more, I think it would be wise to add some documentation and nfc 
bindings examples.

I'm using it as a subnode of an i2c node as such:

&i2c2 {
	pinctrl-names = "default";
	pinctrl-0 = <&i2c2_pins_a>;
	status = "okay";

	pn532: pn53x@48 {
		compatible = "nxp,pn532-i2c";
		reg = <0x48>;
	};
};

But not sure if this is correct at all (I haven't gotten it to work yet, 
partly due to a burnt level shifter). For example, I'm not sure what 
other properties are needed.
