2015-10-27NFC: st-nci: Add ese-present/uicc-present dts propertiesChristophe Ricard2-1/+15
In order to align with st21nfca, dts configuration properties ese_present and uicc_present are made available in st-nci driver. So far, in early development firmware, because nci_nfcee_mode_set(DISABLE) was not supported we had to try to enable it during the secure element discovery phase. After several trials on commercial and qualified firmware it appears that nci_nfcee_mode_set(ENABLE) and nci_nfcee_mode_set(DISABLE) are properly supported. Such feature also help us to eventually save some time (~5ms) when only one secure element is connected.

STMicroelectronics NFC NCI chips family is extending with the new ST21NFCC using the AMS AS39230 RF booster. The st21nfcb driver is relevant for this solution and might be with future products.

2015-06-08NFC: trf7970a: Handle extra byte in response to Type 5 RMB commandsMark A. Greer1-0/+4
The current versions of the trf7970a has an erratum where it returns an extra byte in the response to 'Read Multiple Block' (RMB) commands. This command is issued to Type 5 tags (i.e., ISO/IEC 15693 tags) by the neard daemon. To handle this, define a new Device Tree property, 't5t-rmb-extra-byte-quirk', which indicates that the associated trf7970a device has this erratum. The trf7970a device driver will then ensure that the response length to RMB commands is reduced by one byte (for devices with the erratum). Signed-off-by: Mark A.

2015-01-28NFC: dts: st21nfca: Document ese-present & uicc-present DTS propertyChristophe Ricard1-0/+7
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>

2014-09-24NFC: dts: st21nfcb_i2c: Fix invalid interrupts polarity.Christophe Ricard1-1/+1
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. Greer1-0/+3
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.
