Other functions

---------------

uart_update_timeout(port,cflag,quot)

uart_update_timeout(port,cflag,baud)

	Update the FIFO drain timeout, port->timeout, according to the

	number of bits, parity, stop bits and quotient.

	number of bits, parity, stop bits and baud rate.

	Locking: caller is expected to take port->lock

	Interrupts: n/a

uart_get_baud_rate(port,termios)

uart_get_baud_rate(port,termios,old,min,max)

	Return the numeric baud rate for the specified termios, taking

	account of the special 38400 baud "kludge".  The B0 baud rate

	is mapped to 9600 baud.

	If the baud rate is not within min..max, then if old is non-NULL,

	the original baud rate will be tried.  If that exceeds the

	min..max constraint, 9600 baud will be returned.  termios will

	be updated to the baud rate in use.

	Note: min..max must always allow 9600 baud to be selected.

	Locking: caller dependent.

	Interrupts: n/a

uart_get_divisor(port,termios,oldtermios)

	Return the divsor (baud_base / baud) for the selected baud rate

	specified by termios.  If the baud rate is out of range, try

	the original baud rate specified by oldtermios (if non-NULL).

	If that fails, try 9600 baud.

uart_get_divisor(port,baud)

	Return the divsor (baud_base / baud) for the specified baud

	rate, appropriately rounded.

	If 38400 baud and custom divisor is selected, return the

	custom divisor instead.

	Locking: caller dependent.

	Interrupts: n/a

uart_match_port(port1,port2)

	This utility function can be used to determine whether two

	uart_port structures describe the same port.

	Locking: n/a

	Interrupts: n/a

uart_write_wakeup(port)

	A driver is expected to call this function when the number of

	characters in the transmit buffer have dropped below a threshold.

	Locking: port->lock should be held.

	Interrupts: n/a

uart_register_driver(drv)

	Register a uart driver with the core driver.  We in turn register

	with the tty layer, and initialise the core driver per-port state.

	drv->port should be NULL, and the per-port structures should be

	registered using uart_add_one_port after this call has succeeded.

	Locking: none

	Interrupts: enabled

uart_unregister_driver()

	Remove all references to a driver from the core driver.  The low

	level driver must have removed all its ports via the

	uart_remove_one_port() if it registered them with uart_add_one_port().

	Locking: none

	Interrupts: enabled

uart_suspend_port()

uart_resume_port()

uart_add_one_port()
