+       ---help---
+       The CAIF TTY transport driver is a Line Discipline (ldisc)
+       identified as N_CAIF. When this ldisc is opened from user space
+       it will redirect the TTY's traffic into the CAIF stack.

+       The CAIF Link layer SPI Protocol driver for Slave SPI interface.
+       This driver implements a platform driver to accommodate for a
+       platform specific SPI device. A sample CAIF SPI Platform device is
+       provided in Documentation/networking/caif/spi_porting.txt

+       ---help---
+       Putting the next command and length in the start of the frame can
+       help to synchronize to the next transfer in case of over or under-runs.
+       This option also needs to be enabled on the modem.

+       ---help---
+       The caif low level driver for CAIF over HSI.
+       Be aware that if you enable this then you also need to
+       enable a low-level HSI driver.
