[PATCH v4 0/2] NFC: pn544_i2c: Add device-tree support to PN544

[Clement Perrochaud]

This patch brings device-tree support to the pn544_i2c device
driver.

It has been successfully tested on a BeagleBone Black board - a
common ARM-Based SoC - both as a module and built-in.
Testing involved enabling and disabling the chip, as well as
reading a Type 4 NFC tag. Firmware download has been tested
successfully but was only possible after heavy code modification
out of the scope of this patch.

The submission is broken into two patches: one for code itself and
the second for DTS documentation.

It is based on 48761f6db88da9e733e4405ce9842c0769e4d4ac
(NFC: st21nfca: Implement load_session HCI hook) from the nfc-next master
branch.

Changes from v3:
 - Better handling of errors in case of absence of both platform-data and
device-tree.
 - Implementation of Open Firmware interrupts.
 - Modification if the compatible string to fit device-tree guidelines.
 - Modification of the properties to fit device-tree naming conventions.

Changes from v2:
 - Forgotten documentation patch has been added.
 - pn544_hci_i2c_of_request_resources is now static and takes a struct
i2c_client as argument instead of a struct pn544_i2c_phy.
 - Spacing around operators has been added.
 - Test for device-tree use instead of platform data has been improved.

Changes from v1:
 - Incorrect resource freeing on module removal has been fixed.
 - Compatibility table variable name has been corrected to match
standard pattern.

Both patches applied to nfc-next, thanks a lot.

Cheers,
Samuel.
