Some devices (e.g. Sony's PaSoRi) can not do type B polling, so we have
to make a distinction between ISO14443 type A and B poll modes.Cc: Eric Lapuyade

Sony RC-S360 is also known as the Sony PaSoRi contactless reader.
Only type 2, 3 and 4 tag reading is supported at the moment.Signed-off-by: Samuel Ortiz

Some NFC chips will statically create and open pipes for both standard
and proprietary gates. The driver can now pass this information to HCI
such that HCI will not attempt to create and open them, but will instead
directly use the passed pipe ids.Signed-off-by: Eric Lapuyade

When receiving a DEP link down event, we should cancel all pending URBs
if we're activated as a target or if we're an initiator.Signed-off-by: Samuel Ortiz

After going through all the modulations, the pn533 driver spends 2
seconds listening for targets.Signed-off-by: Samuel Ortiz

Without those settings several devices will not activate pn533 as a target.

When trying to enable a DEP link as a passive initiator, pn533 needs to
provide the polling request command payload.Signed-off-by: Samuel Ortiz

This one needs to be called as soon as we are activated as a target, for
the pn533 to receive the first SYMM and keep the LLCP link alive.Signed-off-by: Samuel Ortiz

And rename the initiator mode data exchange ops for consistency sake.

Userspace gets a netlink event upon target mode activation.
The LLCP layer is also signaled when we get an ATR_REQ in order to get
the remote general bytes.Signed-off-by: Samuel Ortiz

We only want to support p2p target mode for now, no host card emulation.

If "buf[0]" is 255 then "len" gets set to 0. The call to
"crc_ccitt(0xffff, buf, len - 2);" casts the "len - 2" to a high
positive number which is ugly.Signed-off-by: Dan Carpenter

This is an NFC driver for NXP pn544.

container_of() works by subtracting the offset of the member. The math
can't really return a zero here. Sometimes people check it when they
actually meant to check something else but in this case we can just
remove the check.Signed-off-by: Dan Carpenter

The NFC Core now caches the active nfc target pointer, thereby avoiding
the need to lookup the target table for each invocation of a driver ops.
Consequently, pn533, HCI and NCI now directly receive an nfc_target
pointer instead of a target index.Cc: Ilan Elias

When buffers on the receiption path exceed 262 bytes, the pn533 uses
a chaining mechanism where the initiator has to send NULL data frames
to fetch the remaining frames.
We do that from a workqueue context while holding the cmd lock. Once the
MI bit is gone, we aggregate the queued received skbs.Signed-off-by: Samuel Ortiz

There is no need for soft IRQ contexts, and workqueues are more flexible.

When calling nfc_dep_link_up, we implicitely are in initiator mode.
Which means we also can provide the general bytes as a function argument,
as all drivers will eventually request them.Signed-off-by: Samuel Ortiz

Download TI NFC init script during nfcwilink open operation,
after the NFC channel is registered with TI shared transport.
TI NFC init script is written in BTS format.
First, read the chip version via a special vendor specific command.
Second, we request the relevant BTS file from the user space, and
then send the BTS commands to the chip.Signed-off-by: Ilan Elias

Without an API for setting and getting the local and remote general bytes,
drivers won't be able to properly establish a DEP link.
This API also allows them to propagate the remote general bytes they get
from the DEP link establishment up to the LLCP layer.Signed-off-by: Samuel Ortiz
