2016-10-28nfc: mei: use module_mei_cl_driver macroTomas Winkler1-22/+1
Replace boilerplate driver registration with module_mei_cl_driver macro in pn544 and microread devices. Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2016-03-09NFC: microread: Drop platform data header fileJean Delvare1-8/+0
Originally I only wanted to drop the unneeded inclusion of <linux/i2c.h>, but then noticed that struct microread_nfc_platform_data isn't actually used, and MICROREAD_DRIVER_NAME is redefined in the only file where it is used, so we can get rid of the header file and dead code altogether.

2015-10-19NFC: microread: Auto-select core moduleJean Delvare1-11/+7
As I understand it, the core nfc_microread module is useless without either the I2C or the MEI access module. So hide NFC_MICROREAD and select it automatically if either NFC_MICROREAD_I2C or NFC_MICROREAD_MEI is selected. This avoids presenting NFC_MICROREAD when neither NFC_MICROREAD_I2C nor NFC_MICROREAD_MEI can be selected.

2015-09-20mei: bus: use mei_cldev_ prefix for the API functionsTomas Winkler1-3/+3

2015-09-20mei: bus: complete variable rename of type struct mei_cl_deviceTomas Winkler1-4/+4
In the commit 5c079ae11921 ("mei: bus: fix drivers and devices names confusion") we set the variables of type struct mei_cl_device to 'cldev' but few places were left out, namely mei_cl_bus.h header and the mei nfc drivers.

2015-09-20mei: bus: add client protocol version to the device aliasTomas Winkler1-1/+1
The device alias now looks like mei:S:uuid:N:* In that way we can bind different drivers to clients with different protocol versions if required. Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Smatch says that skb->data is untrusted so we need to check to make sure that the memcpy() doesn't overflow. Fixes: cfad1ba87150 ('NFC: Initial support for Inside Secure microread') Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

Several files refer to an old address for the Free Software Foundation in the file header comment. Resolve by replacing the address with the URL <http://www.gnu.org/licenses/> so that we do not have to keep updating the header comments anytime the address changes.

2013-09-25NFC: Standardize logging styleJoe Perches3-26/+17
Use standardized styles to minimize coding defects. Always use nfc_<level> where feasible. Add \n to formats where appropriate. Typo "it it" correction. Add #define pr_fmt where appropriate.

2013-06-14NFC: Remove the static supported_se fieldSamuel Ortiz1-4/+2
Supported secure elements are typically found during a discovery process initiated when the NFC controller is up and running. For a given NFC chipset there can be many configurations (embedded SE or not, with or without a SIM card wired to the NFC controller SWP interface, etc...) and thus driver code will never know before hand which SEs are available. So we remove this field, it will be replaced by a real SE discovery mechanism. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-05-21NFC: mei: Do not disable MEI devices from their remove routineSamuel Ortiz1-2/+0

2013-05-21NFC: mei_phy: Register event callback when enabling the deviceSamuel Ortiz1-13/+5
The callback registration starts a waiting read, so it needs to be fired everytime the device is enabled. Otherwise following writes will never get an answer back. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-04-16NFC: mei: Add a common mei bus API for NFC driversEric Lapuyade2-131/+10
This isolates the common code that is required to use an mei bus nfc device from an NFC HCI drivers. This prepares for future drivers for NFC chips connected behind an Intel Management Engine controller. The microread_mei HCI driver is also modified to use that common code.

2013-02-11NFC: microread: Fix mei physical layerSamuel Ortiz1-19/+24
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>
