40af86a40c NFC: st21nfca: Remove gpio_irq field in static and dts configuration
- phy->gpio_irq is never done out of the request resources.
- irq_of_parse_and_map is already done in the i2c core so client->irq is
already set when entering in st21nfca_hci_i2c_of_request_resources
- In case of static platform configuration client->irq can be set directly
- It simplifies the code a bit.

384ab1d174 NFC: digital: Add NFC-DEP Initiator-side ATN Support
When an NFC-DEP Initiator times out when waiting for

than 'N(retry,atn)' are to be send where
2 <= 'N(retry,atn)' <= 5.  If the Initiator had just
sent a NACK PDU when the timeout occurred, it is to
continue sending NACKs until 'N(retry,nack)' NACKs
have been send.  This is described in section
14.12.5.6 of the NFC-DEP Digital Protocol Spec.

49dbb14e30 NFC: digital: Add NFC-DEP Target-side NACK Support
When an NFC-DEP Target receives a NACK PDU with
a PNI equal to 1 less than the current PNI, it
is supposed to re-send the last PDU.  This is
implied in section 14.12.5.4 of the NFC Digital

The digital layer's NFC-DEP code doesn't implement
Target-side NACK handing so add it.  The last PDU
that was sent is saved in the 'nfc_digital_dev'
structure's 'saved_skb' member.  The skb will have
an additional reference taken to ensure that the skb
isn't freed when the driver performs a kfree_skb()
on the skb.  The length of the skb/PDU is also saved
so the length can be restored when re-sending the PDU
in the skb (the driver will perform an skb_pull() so
an skb_push() needs to be done to restore the skb's
data pointer/length).

a80509c76b NFC: digital: Add NFC-DEP Initiator-side NACK Support
When an NFC-DEP Initiator receives a frame with
an incorrect CRC or with a parity error, and the
frame is at least 4 bytes long, its supposed to
send a NACK to the Target.  The Initiator can
send up to 'N(retry,nack)' consecutive NACKs
where 2 <= 'N(retry,nack)' <= 5.  When the limit
is exceeded, a PROTOCOL EXCEPTION is raised.
Any other type of transmission error is to be
ignored and the Initiator should continue
waiting for a new frame.  This is described
in section 14.12.5.4 of the NFC Digital Protocol
Spec.

The digital layer's NFC-DEP code doesn't implement
any of this so add it.  This support diverges from
the spec in two significant ways:

a) NACKs will be sent for ANY error reported by the
   driver except a timeout.  This is done because
   there is currently no way for the digital layer
   to distinguish a CRC or parity error from any
   other type of error reported by the driver.

b) All other errors will cause a PROTOCOL EXCEPTION
   even frames with CRC errors that are less than 4
   bytes.

The value chosen for 'N(retry,nack)' is 2.

Targets do not send NACK PDUs.

c12715ab3f NFC: digital: Add NFC-DEP Receive Chaining Support
When the peer in an NFC-DEP exchange has a
packet to send that is larger than the local
maximum payload, it sets the 'MI' bit in the
'I' PDU.  This indicates that NFC-DEP chaining
is to occur.

When such a PDU is received, the local side
responds with an 'ACK' PDU and this continues
until the peer sends an 'I' PDU with the 'MI'
bit cleared.  This indicates that the chaining
sequence is complete and the entire packet has
been transferred.

Receiving chained PDUs is currently not supported
by the digital layer so add that support.  When a
chaining sequence is initiated by the peer, the
digital layer will allocate an skb large enough
to hold 8 maximum sized frame payloads.  The maximum
payload can range from 64 to 254 bytes so 8 * 254 =
2032 seems like a reasonable compromise between
potentially wasting memory and constantly reallocating
new, larger skbs.

3bd2a5bcc6 NFC: digital: Add NFC-DEP Send Chaining Support
When the NFC-DEP code is given a packet to send
that is larger than the peer's maximum payload,
its supposed to set the 'MI' bit in the 'I' PDU's
Protocol Frame Byte (PFB).  Setting this bit
indicates that NFC-DEP chaining is to occur.

When NFC-DEP chaining is progress, sender 'I' PDUs
are acknowledged with 'ACK' PDUs until the last 'I'
PDU in the chain (which has the 'MI' bit cleared)
is responded to with a normal 'I' PDU.  This can
occur while in Initiator mode or in Target mode.

Sender NFC-DEP chaining is currently not implemented
in the digital layer so add that support.  Unfortunately,
since sending a frame may require writing the CRC to the
end of the data, the relevant data part of the original
skb must be copied for each intermediate frame.

b08147cbc4 NFC: digital: Implement NFC-DEP max payload lengths
The maximum payload for NFC-DEP exchanges (i.e., the
number of bytes between SoD and EoD) is negotiated
using the ATR_REQ, ATR_RES, and PSL_REQ commands.
The valid maximum lengths are 64, 128, 192, and 254
bytes.

Currently, NFC-DEP code assumes that both sides are
always using 254 byte maximums and ignores attempts
by the peer to change it.  Instead, implement the
negotiation code, enforce the local maximum when
receiving data from the peer, and don't send payloads
that exceed the remote's maximum.  The default local
maximum is 254 bytes.

05afedcb89 NFC: digital: Add Target-mode NFC-DEP DID Support
When in Target mode, the Initiator specifies whether
subsequent DEP_REQ and DEP_RES frames will include
a DID byte by the value passed in the ATR_REQ.  If
the DID value in the ATR_REQ is '0' then no DID
byte will be included.  If the DID value is between
'1' and '14' then a DID byte containing the same
value must be included in subsequent DEP_REQ and
DEP_RES frames.  Any other DID value is invalid.
This is specified in sections 14.8.1.2 and 14.8.2.2
of the NFC Digital Protocol Spec.

Checking the DID value (if it should be there at all),
is not currently supported by the digital layer's
NFC-DEP code.  Add this support by remembering the
DID value in the ATR_REQ, checking the DID value of
received DEP_REQ frames (if it should be there at all),
and including the remembered DID value in DEP_RES
frames when appropriate.

If the corresponding option is set to 'y', the build system will then

a831f20b6d wireless/p54: Remove duplicated net2280 header
The usb gadget driver net2280 has exported a header file with the
register definition of the net2280 chip.

Remove the custom/duplicated header file in favor of that header file
in include/linux

c15d789e3c brcmfmac: fix static checker warning in pmklist handling
The patch fixes a static checker warning:

   drivers/net/wireless/brcm80211/brcmfmac/cfg80211.c:2965
      brcmf_cfg80211_set_pmksa()
	warn: can 'pmkid_len' be negative?

The answer to the question above is likely no so changing its
type to unsigned is sufficient.

ef16ea32db Major works are CSA and TDLS. On top of that I have a new
firmware API for scan and a few rate control improvements.
 Johannes find a few tricks to improve our CPU utilization
 and adds support for a new spin of 7265 called 7265D.
 Along with this a few random things that don't stand out.

2021a89d7b iwlwifi: mvm: treat netdetect wake up separately
When the device wakes up due to netdetect, we need to query different
things from the firmware than when it wakes up with a normal WoWLAN.
To make this easier, separate the netdetect wake up handling from the
rest.  For now, we don't send netdetect as a wake up reason, treating
it as a non-wireless wake up.
