1	What:		/sys/devices/platform/kim/dev_name
2	Date:		January 2010
3	KernelVersion:	2.6.38
4	Contact:	"Pavan Savoy" <pavan_savoy@ti.com>
5	Description:
6			Name of the UART device at which the WL128x chip
7			is connected. example: "/dev/ttyS0".
8			The device name flows down to architecture specific board
9			initialization file from the SFI/ATAGS bootloader
10			firmware. The name exposed is read from the user-space
11			dameon and opens the device when install is requested.
13	What:		/sys/devices/platform/kim/baud_rate
14	Date:		January 2010
15	KernelVersion:	2.6.38
16	Contact:	"Pavan Savoy" <pavan_savoy@ti.com>
17	Description:
18			The maximum reliable baud-rate the host can support.
19			Different platforms tend to have different high-speed
20			UART configurations, so the baud-rate needs to be set
21			locally and also sent across to the WL128x via a HCI-VS
22			command. The entry is read and made use by the user-space
23			daemon when the ldisc install is requested.
25	What:		/sys/devices/platform/kim/flow_cntrl
26	Date:		January 2010
27	KernelVersion:	2.6.38
28	Contact:	"Pavan Savoy" <pavan_savoy@ti.com>
29	Description:
30			The WL128x makes use of flow control mechanism, and this
31			entry most often should be 1, the host's UART is required
32			to have the capability of flow-control, or else this
33			entry can be made use of for exceptions.
35	What:		/sys/devices/platform/kim/install
36	Date:		January 2010
37	KernelVersion:	2.6.38
38	Contact:	"Pavan Savoy" <pavan_savoy@ti.com>
39	Description:
40			When one of the protocols Bluetooth, FM or GPS wants to make
41			use of the shared UART transport, it registers to the shared
42			transport driver, which will signal the user-space for opening,
43			configuring baud and install line discipline via this sysfs
44			entry. This entry would be polled upon by the user-space
45			daemon managing the UART, and is notified about the change
46			by the sysfs_notify. The value would be '1' when UART needs
47			to be opened/ldisc installed, and would be '0' when UART
48			is no more required and needs to be closed.
