config CAIF_TTY
tristate "CAIF TTY transport driver"
depends on CAIF && TTY
default n
---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.
config CAIF_SPI_SLAVE
tristate "CAIF SPI transport driver for slave interface"
depends on CAIF && HAS_DMA
default n
---help---
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
config CAIF_SPI_SYNC
bool "Next command and length in start of frame"
depends on CAIF_SPI_SLAVE
default n
---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.
config CAIF_HSI
tristate "CAIF HSI transport driver"
depends on CAIF
default n
---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.
config CAIF_VIRTIO
tristate "CAIF virtio transport driver"
depends on CAIF && HAS_DMA
select VHOST_RING
select VIRTIO
select GENERIC_ALLOCATOR
default n
---help---
The caif driver for CAIF over Virtio.
