Loading a firmware into a target is typically called firmware download, not firmware upload. So we rename the netlink API to NFC_CMD_FW_DOWNLOAD in order to avoid any terminology confusion from userspace. Signed-off-by: NSamuel Ortiz <sameo@linux.intel.com>

Enabling or disabling an NFC accessible secure element through netlink requires giving both an NFC controller and a secure element indexes. Once enabled the secure element will handle card emulation once polling starts. Signed-off-by: NSamuel Ortiz <sameo@linux.intel.com>

由 Samuel Ortiz 提交于
When an NFC driver or host controller stack discovers a secure element, it will call nfc_add_se(). In order for userspace applications to use these secure elements, a netlink event will then be sent with the SE index and its type. With that information userspace applications can decide wether or not to enable SEs, through their indexes. Signed-off-by: NSamuel Ortiz <sameo@linux.intel.com>

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: NSamuel Ortiz <sameo@linux.intel.com>

As several NFC chipsets can have their firmwares upgraded and reflashed, this patchset adds a new netlink command to trigger that the driver loads or flashes a new firmware. This will allows userspace triggered firmware upgrade through netlink. The firmware name or hint is passed as a parameter, and the driver will eventually fetch the firmware binary through the request_firmware API. The cmd can only be executed when the nfc dev is not in use. Actual firmware loading/flashing is an asynchronous operation. Result of the operation shall send a new event up to user space through the nfc dev multicast socket. During operation, the nfc dev is not openable and thus not usable.

This adds a netlink interface for service name lookup support. Multiple URIs can be passed nested into the NFC_ATTR_LLC_SDP attribute using the NFC_CMD_LLC_SDREQ netlink command. When the SNL reply is received, a NFC_EVENT_LLC_SDRES event is sent to the user space. URI and SAP tuples are passed back, nested into NFC_ATTR_LLC_SDP attribute.

Each NFC adapter can have several links to different secure elements and that property needs to be exported by the drivers. A secure element link can be enabled and disabled, and card emulation will be handled by the currently active one. Otherwise card emulation will be host implemented.

NFC_CMD_LLC_GET_PARAMS: request LTO, RW, and MIUX parameters for a device NFC_CMD_LLC_SET_PARAMS: set one or more of LTO, RW, and MIUX parameters for a device. LTO must be set before the link is up otherwise -EINPROGRESS is returned. RW and MIUX can be set at anytime and will be passed in subsequent CONNECT and CC messages.
