I dived into lguest again, reworking the pagetable code so we can move the switcher page: our fixmaps sometimes take more than 2MB now...

Annoying conflicts with the tcm_vhost -> vhost_scsi rename.

|
|
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

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.
