SFI-based platforms are gone. So does this framework. This removes mention of SFI through the drivers and other code as well.

Description:
|
|
Name of the UART device at which the WL128x chip
|
|
is connected. example: "/dev/ttyS0".
|
|
|
|
The device name flows down to architecture specific board
|
|
initialization file from the ATAGS bootloader
|
|
firmware. The name exposed is read from the user-space
|
|
dameon and opens the device when install is requested.

|
|
Description:
|
|
The maximum reliable baud-rate the host can support.
|
|
Different platforms tend to have different high-speed
|
|
UART configurations, so the baud-rate needs to be set
|
|
locally and also sent across to the WL128x via a HCI-VS
|
|
command. The entry is read and made use by the user-space
|
|
daemon when the ldisc install is requested.

|
|
Description:
|
|
The WL128x makes use of flow control mechanism, and this
|
|
entry most often should be 1, the host's UART is required
|
|
to have the capability of flow-control, or else this
|
|
entry can be made use of for exceptions.

Description:
|
|
When one of the protocols Bluetooth, FM or GPS wants to make
|
|
use of the shared UART transport, it registers to the shared
|
|
transport driver, which will signal the user-space for opening,
|
|
configuring baud and install line discipline via this sysfs
|
|
entry. This entry would be polled upon by the user-space
|
|
daemon managing the UART, and is notified about the change
|
|
by the sysfs_notify. The value would be '1' when UART needs
|
|
to be opened/ldisc installed, and would be '0' when UART
|
|
is no more required and needs to be closed.
