NFC: Standardize logging style

2013-09-24T23:35:39Z

Use standardized styles to minimize coding defects. Always use nfc_ where feasible. Add \n to formats where appropriate. Typo "it it" correction. Add #define pr_fmt where appropriate. Remove function tracing logging messages. Remove OOM messages. Signed-off-by: Joe Perches Signed-off-by: Samuel Ortiz

NFC: pn544: Add SE enable/disable operation

2013-09-24T23:35:39Z

To enable the UICC secure element, we first enable the UICC gate list in order for the SE to be able to use all RF technologies. For the embedded SE, we just turn the eSE default mode to ON. Signed-off-by: Arron Wang Signed-off-by: Samuel Ortiz

NFC: pn544: Add SE discover operation

2013-09-24T23:35:38Z

For the SWP secure element, we send the proprietary SELF_TEST_SWP command and check the response. For the WI secure element, we simply try to switch to the default embedded SE mode. If that works, it means we have an embedded SE. Signed-off-by: Arron Wang Signed-off-by: Samuel Ortiz

NFC: pn544: i2c: Add firmware download implementation for pn544

2013-08-13T23:13:35Z

The pn544 can enter a firmware update mode where firmware blobs can be pushed through the i2c line and flashed on the target. A special command allows to verify that blobs are correctly flashed and this is what we do for every downloaded firmware blob. Signed-off-by: Eric Lapuyade Signed-off-by: Samuel Ortiz

NFC: pn544: Add firmware operations hci ops

2013-08-13T23:13:33Z

The firmware operation callback is passed by the physical layer to the hci driver during probe. All the driver does is to store it and call it when the fw_upload hci ops is invoked. Signed-off-by: Eric Lapuyade Signed-off-by: Samuel Ortiz

NFC: pn544: i2c: Add firmware download mode power-on support

2013-08-13T23:08:12Z

This is in preparation for pn544-i2c firmware download feature, where we need to know if we're in regular or firmware upload mode. Signed-off-by: Eric Lapuyade Signed-off-by: Samuel Ortiz

NFC: Remove the static supported_se field

2013-06-14T11:44:19Z

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

NFC: pn544: Remove Felica and Jewel device presence check

2013-06-13T22:18:58Z

There is no builtin command for driver to check the presence of Felica and Jewel device, it is more reasonable for the userspace daemon neard to build seperate commands to check the presence of the card. Signed-off-by: Arron Wang Signed-off-by: Samuel Ortiz

NFC: pn544: Identify Type F NFC-DEP through NFCID2

2013-06-13T22:18:58Z

NFCID2 is defined as the first 2 manufacturer ID (IDm) bytes. NFC DEP (NFC peer to peer) devices Type-F NFCID2 must start with 0x01fe according to the NFC Digital Specification. By checking those first 2 bytes we send the right command either to the reader gate when NFCID2 != 0x1fe (The NFC tag case) or to the NFCIP1 gate when seeing an NFC DEP device (The NFC peer to peer case). Without this fix, Felica (Type F) tags are not properly detected with this driver. Signed-off-by: Arron Wang Signed-off-by: Samuel Ortiz

NFC: mei: Do not disable MEI devices from their remove routine

2013-05-21T08:48:41Z

Enabling and disabling device is exclusively handled by the mei_phy_ops. Signed-off-by: Samuel Ortiz
