^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) 		The maximum reliable baud-rate the host can support.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) 		Different platforms tend to have different high-speed
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) 		UART configurations, so the baud-rate needs to be set
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) 		locally and also sent across to the WL128x via a HCI-VS
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) 		command. The entry is read and made use by the user-space
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) 		daemon when the ldisc install is requested.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) 		entry most often should be 1, the host's UART is required
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) 		to have the capability of flow-control, or else this

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) 		When one of the protocols Bluetooth, FM or GPS wants to make
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 42) 		use of the shared UART transport, it registers to the shared
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 43) 		transport driver, which will signal the user-space for opening,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 44) 		configuring baud and install line discipline via this sysfs
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 45) 		entry. This entry would be polled upon by the user-space
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) 		daemon managing the UART, and is notified about the change
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 47) 		by the sysfs_notify. The value would be '1' when UART needs
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 48) 		to be opened/ldisc installed, and would be '0' when UART
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 49) 		is no more required and needs to be closed.
