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" +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" +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 +Contact: "Pavan Savoy" +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. -- cgit v1.2.3
