2015-03-26NFC: nxp-nci_i2c: Add I2C support to NXP NCI driverClément Perrochaud
Add a module to the NXP-NCI driver to support NFC controllers with an I2C control interface, such as the NPC100. Signed-off-by: Clément Perrochaud <clement.perrochaud@effinnov.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2015-01-28NFC: dts: st21nfca: Document ese-present & uicc-present DTS propertyChristophe Ricard
On st21nfca, the mechanism to enable a secure element needs to add 2 properties in order manage the SWP line correctly. Document ese-present and uicc-present properties. Signed-off-by: Christophe Ricard <christophe-h.ricard@st.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2015-01-26NFC: dts: st21nfcb: Fix compatible string spelling to follow other driversChristophe Ricard
Other drivers are following the following compatible string format for dts: s/_/-/ Because some devices may still use the previous string, the new corrected string is added to the of_device_id table.

2014-09-24NFC: dts: st21nfcb_i2c: Fix invalid interrupts polarity.Christophe Ricard
St21nfcb has a reverse polarity compare to st21nfca. In st21nfcb case, the irq pin is active high. Signed-off-by: Christophe Ricard <christophe-h.ricard@st.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2014-09-01NFC: trf7970a: Document the 'en2-rf-quirk' DT propertyMark A. Greer
Current versions of the trf7970a have an erratum where the EN2 pin must be kept low. If it isn't kept low, it will generate an RF field even when in passive target mode. To work around this issue, create the 'en2-rf-quirk' device tree property to indicate that the trf7970a that the driver is using has this erratum. Signed-off-by: Mark A.

2014-09-01NFC: trf7970a: Document the 'irq-status-read-quirk' DT propertyMark A. Greer
The mechanism for specifying that the trf7970a being used by the driver has the "IRQ Status Read" erratum has been changed to a device tree property ('irq-status-read-quirk'). Document the new device tree property. Signed-off-by: Mark A. Greer <mgreer@animalcreek.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2014-09-01NFC: trf7970a: Document the 'vin-voltage-override' DTS propertyMark A. Greer
The trf7970a driver recently had support for the 'vin-voltage-override' property added to it. This property is used to override the value given by the regulator subsystem for the VIN pin's voltage.

2014-05-26NFC: dts: st21nfca_i2c: Correct minor typo in documentationChristophe Ricard
Replaced st,st21nfca-i2c by st,st21nfca_i2c to be concistent with below configuration and driver in drivers/nfc/st21nfca/ Signed-off-by: Christophe Ricard <christophe-h.ricard@st.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
