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. * If one of the passed parameters is wrong none is set and -EINVAL is * returned. * @NFC_CMD_ENABLE_SE: Enable the physical link to a specific secure element. * Once enabled a secure element will handle card emulation mode, i.e. * starting a poll from a device which has a secure element enabled means * we want to do SE based card emulation. * @NFC_CMD_DISABLE_SE: Disable the physical link to a specific secure element. * @NFC_CMD_FW_DOWNLOAD: Request to Load/flash firmware, or event to inform * that some firmware was loaded * @NFC_EVENT_SE_ADDED: Event emitted when a new secure element is discovered. * This typically will be sent whenever a new NFC controller with either * an embedded SE or an UICC one connected to it through SWP. * @NFC_EVENT_SE_REMOVED: Event emitted when a secure element is removed from * the system, as a consequence of e.g. an NFC controller being unplugged. * @NFC_EVENT_SE_CONNECTIVITY: This event is emitted whenever a secure element * is requesting connectivity access. For example a UICC SE may need to * talk with a sleeping modem and will notify this need by sending this * event. It is then up to userspace to decide if it will wake the modem * up or not. * @NFC_EVENT_SE_TRANSACTION: This event is sent when an application running on
