Hi John,
This is the first NFC pull request for the 3.13 kernel.
It's a fairly big one, with the following highlights:
- NFC digital layer implementation: Most NFC chipsets implement the NFC
digital layer in firmware, but others have more basic functionalities
and expect the host to implement the digital layer. This layer sits
below the NFC core.
- Sony's port100 support: This is "soft" NFC USB dongle that expects the
digital layer to be implemented on the host. This is the first user of
our NFC digital stack implementation.
- Secure element API: We now provide a netlink API for enabling,
disabling and discovering NFC attached (embedded or UICC ones) secure
elements. With some userspace help, this allows us to support NFC
payments.
Only the pn544 driver currently supports that API.
- NCI SPI fixes and improvements: In order to support NCI devices over
SPI, we fixed and improved our NCI/SPI implementation. The currently
most deployed NFC NCI chipset, Broadcom's bcm2079x, supports that mode
and we're planning to use our NCI/SPI framework to implement a
driver for it.
- pn533 fragmentation support in target mode: This was the only missing
feature from our pn533 impementation. We now support fragmentation in
both Tx and Rx modes, in target mode.
