After fixing the LLC Makefile, we no longer need those exports. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-09-25NFC: Changed HCI and PN544 HCI driver to use the new HCI LLC CoreEric Lapuyade
The previous shdlc HCI driver and its header are removed from the tree. PN544 now registers directly with HCI and passes the name of the llc it requires (shdlc). HCI instantiation now allocates the required llc instance. The llc is started when the HCI device is brought up.

2012-09-25NFC: Add an shdlc llc module to llc coreEric Lapuyade
This is used by HCI drivers such as the one for the pn544 which require communications between HCI and the chip to use shdlc. Signed-off-by: Eric Lapuyade <eric.lapuyade@intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-09-25NFC: Add a nop (passthrough) llc module to llc coreEric Lapuyade
This is a passthrough llc. It can be used by HCI drivers that don't need link layer control. HCI will then write directly to the driver, and driver will deliver incoming frames directly to HCI without any processing.

2012-09-25NFC: Add an LLC Core layer to HCIEric Lapuyade
The LLC layer manages modules that control the link layer protocol (such as shdlc) between HCI and an HCI driver. The driver must simply specify the required llc when it registers with HCI. Signed-off-by: Eric Lapuyade <eric.lapuyade@intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-09-25NFC: Modified hci_transceive to become an asynchronous operationEric Lapuyade
This enables the completion callback to be called from a different context, preventing a possible deadlock if the callback resulted in the invocation of a nested call to the currently locked nfc_dev. This is also more in line with the im_transceive nfc_ops for NFC Core or NCI drivers which already behave asynchronously.

2012-09-25NFC: Remove crc generation from shdlc layerWaldemar Rymarkiewicz
Checksum is specific for a chip spcification and it varies (in size and type) between different hardware. It should be handled in the driver then. Moreover, shdlc spec doesn't mention crc as a part of the frame. Update pn544_hci driver as well.

2012-09-25NFC: Set the IRQF_ONESHOT flag from the pn544_hci IRQ handler requestSamuel Ortiz
As we don't have a primary handler but only a threaded one, __setup_irq() ends up failing if we don't set this flag. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-09-25NFC: Don't use WQ_MEM_RECLAIM for pn533Tejun Heo
NFC driver doesn't sit in memory reclaim path and has no reason to use WQ_MEM_RECLAIM. Drop WQ_MEM_RECLAIM from pn533->wq and use alloc_ordered_workqueue() instead of WQ_UNBOUND w/ max_active == 1. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-09-25NFC: Use system_nrt_wq instead of custom onesTejun Heo
NFC is using a number of custom ordered workqueues w/ WQ_MEM_RECLAIM. WQ_MEM_RECLAIM is unnecessary unless NFC is gonna be used as transport for storage device, and all use cases match one work item to one ordered workqueue - IOW, there's no actual ordering going on at all and using system_nrt_wq gives the same behavior. There's nothing to be gained by using custom workqueues. Use system_nrt_wq instead and drop all the custom ones.

2012-09-25NFC: Queue pn533 commandsSamuel Ortiz
Instead of returning EBUSY when getting a command while another one is running, we queue them. Upon completion of the pending command, the next one is processed. Besides the fact that it simplifies the pn533 locking scheme, it also comes with the nice side effect of fixing the following warning: [ 82.274297] ===================================== [ 82.274297] [ BUG: bad unlock balance detected! ] [ 82.274298] 3.5.0-rc1+ #1 Not tainted [ 82.274299] ------------------------------------- [ 82.274300] kworker/u:1/16 is trying to release lock (&dev->cmd_lock) at: [ 82.274305] [<ffffffff8144f246>] mutex_unlock+0x9/0xb [ 82.274305] but there are no more locks to release!
