2013-02-11NFC: microread: Fix mei physical layerSamuel Ortiz
The MEI bus API changed according to the latest comments from the char-misc maintainers, and this patch fixes the microread mei physical layer code according to those changes: We pass the MEI id back to the probe routine, and the mei_driver takes a table of MEI ids instead of one static id. Also, mei_bus_driver got renamed to mei_driver, mei_bus_client to mei_device, and mei_bus_set/get_clientdata to mei_set/get_clientdata. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2013-01-10NFC: pn533: Fix missing parenthesisWaldemar Rymarkiewicz
This is a quite critical patch as it fixes potential reference to undefined general_bytes which were never set correctly on target activation due to missing parenthesis. Signed-off-by: Waldemar Rymarkiewicz <waldemar.rymarkiewicz@tieto.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-01-10NFC: Initial Secure Element APISamuel Ortiz
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.

2013-01-10NFC: pn544: Separate the core code and the i2c one into different modulesSamuel Ortiz
As we may need to support other physical layers, we can avoid linking the core part into each and every pn544 module. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-01-10NFC: Add HCI quirks to support driver (non)standard implementationsEric Lapuyade
Some chips diverge from the HCI spec in their implementation of standard features. This adds a new quirks parameter to nfc_hci_allocate_device() to let the driver indicate its divergence. Signed-off-by: Eric Lapuyade <eric.lapuyade@intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2013-01-10NFC: Changed event_received hci ops result semanticEric Lapuyade
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.

2013-01-10NFC: nfcwilink: Use devm_kzallocJulia Lawall
devm_kzalloc allocates memory that is released when a driver detaches.

2013-01-10NFC: pn533: Introduce ops for frame logicWaldemar Rymarkiewicz

2013-01-10NFC: pn533: Use skb in __pn533_send_cmd_frame_asynWaldemar Rymarkiewicz
__pn533_send_cmd_frame_async() should be frame type independent. So, don't use pn533_frame type params and instead use skb for req and resp pointers. Signed-off-by: Waldemar Rymarkiewicz <waldemar.rymarkiewicz@tieto.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2013-01-10NFC: pn533: Add a new pn533_send_sync ifaceWaldemar Rymarkiewicz
It is intended to replace pn533_send_cmd_frame_sync() iface which requires from the caller to create complete frame. The new function constructs a complete frame itself and sends it out in sync manner. This way frame logic is hidden from the caller. pn533_send_cmd_sync() returns ERR_PTR in case of an error or a pointer to valid response sk_buff otherwise. The pointer must be freed by the caller when it's been consumed. Signed-off-by: Waldemar Rymarkiewicz <waldemar.rymarkiewicz@tieto.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-01-10NFC: pn533: Add a new pn533_send_data_async ifaceWaldemar Rymarkiewicz
This iface is intended to be used with DEP transfers. It differs from pn533_send_cmd_async() in the way the response skb is allocated. Signed-off-by: Waldemar Rymarkiewicz <waldemar.rymarkiewicz@tieto.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-01-10NFC: pn533: Add a new pn533_send_cmd_async ifaceWaldemar Rymarkiewicz
This is intendend to replace pn533_send_cmd_frame_async() which requires from the caller to create a complete frame. The new function constructs a frame and sends it out which hides the frame logic and avoid code duplication. The caller has to allocate skb and put its payload there, and finally provide the skb together with a complete cb to pn533_send_cmd_async(). Response skb is allocated by the core part and pass to the caller cb. Next, the caller has to free it when is not needed anymore or pass it up to the stack.

2013-01-10NFC: pn533: Remove pointless flags paramWaldemar Rymarkiewicz

2013-01-03Drivers: misc: remove __dev* attributes.Greg Kroah-Hartman
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.
