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

|
||
|
|
provided in Documentation/networking/caif/spi_porting.txt

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.
