SubjectRe: [PATCH 00/11] NFC: pn533: bug fixes and improvements
Date
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.
