Eric Lapuyade 06c660340f NFC: pn544: i2c: Add firmware download implementation for pn544
The pn544 can enter a firmware update mode where firmware blobs can be
pushed through the i2c line and flashed on the target.
A special command allows to verify that blobs are correctly flashed and
this is what we do for every downloaded firmware blob.

Eric Lapuyade 8bd7fc8995 NFC: pn544: Add firmware operations hci ops
The firmware operation callback is passed by the physical layer to the
hci driver during probe. All the driver does is to store it and call it
when the fw_upload hci ops is invoked.

Eric Lapuyade eab10b71a7 NFC: pn544: i2c: Add firmware download mode power-on support
This is in preparation for pn544-i2c firmware download feature, where we
need to know if we're in regular or firmware upload mode.

Samuel Ortiz 0b456c418a NFC: Remove the static supported_se field
Supported secure elements are typically found during a discovery process
initiated when the NFC controller is up and running. For a given NFC
chipset there can be many configurations (embedded SE or not, with or
without a SIM card wired to the NFC controller SWP interface, etc...) and
thus driver code will never know before hand which SEs are available.
So we remove this field, it will be replaced by a real SE discovery
mechanism.

Arron Wang a69bdc1ecd NFC: pn544: Remove Felica and Jewel device presence check
There is no builtin command for driver to check the presence of
Felica and Jewel device, it is more reasonable for the userspace
daemon neard to build seperate commands to check the presence of
the card.

Arron Wang 9c59844005 NFC: pn544: Identify Type F NFC-DEP through NFCID2
NFCID2 is defined as the first 2 manufacturer ID (IDm) bytes.
NFC DEP (NFC peer to peer) devices Type-F NFCID2 must start with
0x01fe according to the NFC Digital Specification.
By checking those first 2 bytes we send the right command either to the
reader gate when NFCID2 != 0x1fe (The NFC tag case) or to the NFCIP1 gate
when seeing an NFC DEP device (The NFC peer to peer case).

Without this fix, Felica (Type F) tags are not properly detected with this
driver.

Samuel Ortiz 390a1bd853 NFC: Initial Secure Element API
Each NFC adapter can have several links to different secure elements and
that property needs to be exported by the drivers.
A secure element link can be enabled and disabled, and card emulation will
be handled by the currently active one. Otherwise card emulation will be
host implemented.

Eric Lapuyade bf71ab8ba5 NFC: Add HCI quirks to support driver (non)standard implementations

Eric Lapuyade 40d06d3647 NFC: Changed event_received hci ops result semantic
Some chips use a standard HCI event code, destined to a proprietary
gate, with a different meaning. Therefore, the HCI driver must always
have a chance to intercept the event before standard processing is
attempted.
The new semantic specifies that the result value "1" means that the
driver doesn't especially handle the event. result <= 0 means it was
handled.

Greg Kroah-Hartman 0fe763c570 Drivers: misc: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

The driver now has all HCI stuff isolated in one file, and all the
hardware link specifics in another. Writing a pn544 driver on top of
another hardware link is now just a matter of adding a new file for that
new hardware specifics.
