| 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 SFI/ATAGS bootloader | |
| firmware. The name exposed is read from the user-space | |
| dameon and opens the device when install is requested. | |
| What: /sys/devices/platform/kim/baud_rate | |
| Date: January 2010 | |
| KernelVersion: 2.6.38 | |
| Contact: "Pavan Savoy" <pavan_savoy@ti.com> | |
| 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. | |
| What: /sys/devices/platform/kim/flow_cntrl | |
| Date: January 2010 | |
| KernelVersion: 2.6.38 | |
| Contact: "Pavan Savoy" <pavan_savoy@ti.com> | |
| 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. | |
| What: /sys/devices/platform/kim/install | |
| Date: January 2010 | |
| KernelVersion: 2.6.38 | |

| 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. |
