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

69 * starting a poll from a device which has a secure element enabled means
70 * we want to do SE based card emulation.
