The purpose of this patch series is to add a uart phy driver to the pn533 nfc driver. It first changes the dt strings and docs. The dt compatible strings need to change, because I would add "pn532-uart" to the already existing "pn533-i2c" one. These two are now unified into just "pn532". Then the neccessary changes to the pn533 core driver are made. Then the uart phy is added. As the pn532 chip supports a autopoll, I wanted to use this instead of the software poll loop in the pn533 core driver. It is added and activated by the last to patches. The way to add the autopoll later in seperate patches is chosen, to show, that the uart phy driver can also work with the software poll loop, if someone needs that for some reason. This patchset is already rebased on Johans "NFC: pn533: fix use-after-free and memleaks" patch https://lore.kernel.org/netdev/[email protected]/ as they would conflict. If for some reason Johans patch will not get merged, I can of course provide the patchset without depending on this patch.
