/**
 * struct uart_ops -- interface between serial_core and the driver
 *
 * This structure describes all the operations that can be done on the
 * physical hardware.
 *
 * @tx_empty: ``unsigned int ()(struct uart_port *port)``
 *
 *	This function tests whether the transmitter fifo and shifter for the
 *	@port is empty. If it is empty, this function should return
 *	%TIOCSER_TEMT, otherwise return 0. If the port does not support this
 *	operation, then it should return %TIOCSER_TEMT.
 *
 *	Locking: none.
 *	Interrupts: caller dependent.
 *	This call must not sleep
 *
 * @set_mctrl: ``void ()(struct uart_port *port, unsigned int mctrl)``
 *
 *	This function sets the modem control lines for @port to the state
 *	described by @mctrl. The relevant bits of @mctrl are:
 *
 *		- %TIOCM_RTS	RTS signal.
 *		- %TIOCM_DTR	DTR signal.
 *		- %TIOCM_OUT1	OUT1 signal.
 *		- %TIOCM_OUT2	OUT2 signal.
 *		- %TIOCM_LOOP	Set the port into loopback mode.
 *
 *	If the appropriate bit is set, the signal should be driven
 *	active.  If the bit is clear, the signal should be driven
 *	inactive.
 *
 *	Locking: @port->lock taken.
 *	Interrupts: locally disabled.
 *	This call must not sleep
 *
 * @get_mctrl: ``unsigned int ()(struct uart_port *port)``
 *
 *	Returns the current state of modem control inputs of @port. The state
 *	of the outputs should not be returned, since the core keeps track of
 *	their state. The state information should include:
 *
 *		- %TIOCM_CAR	state of DCD signal
 *		- %TIOCM_CTS	state of CTS signal
 *		- %TIOCM_DSR	state of DSR signal
 *		- %TIOCM_RI	state of RI signal
 *
 *	The bit is set if the signal is currently driven active.  If
 *	the port does not support CTS, DCD or DSR, the driver should
 *	indicate that the signal is permanently active. If RI is
 *	not available, the signal should not be indicated as active.
 *
 *	Locking: @port->lock taken.
 *	Interrupts: locally disabled.
 *	This call must not sleep
 *
 * @stop_tx: ``void ()(struct uart_port *port)``
 *
 *	Stop transmitting characters. This might be due to the CTS line
 *	becoming inactive or the tty layer indicating we want to stop
 *	transmission due to an %XOFF character.
 *
 *	The driver should stop transmitting characters as soon as possible.
 *
 *	Locking: @port->lock taken.
 *	Interrupts: locally disabled.
 *	This call must not sleep
 *
 * @start_tx: ``void ()(struct uart_port *port)``
 *
 *	Start transmitting characters.
 *
 *	Locking: @port->lock taken.
 *	Interrupts: locally disabled.
 *	This call must not sleep
 *
 * @throttle: ``void ()(struct uart_port *port)``
 *
 *	Notify the serial driver that input buffers for the line discipline are
 *	close to full, and it should somehow signal that no more characters
 *	should be sent to the serial port.
 *	This will be called only if hardware assisted flow control is enabled.
 *
 *	Locking: serialized with @unthrottle() and termios modification by the
 *	tty layer.
 *
 * @unthrottle: ``void ()(struct uart_port *port)``
 *
 *	Notify the serial driver that characters can now be sent to the serial
 *	port without fear of overrunning the input buffers of the line
 *	disciplines.
 *
 *	This will be called only if hardware assisted flow control is enabled.
 *
 *	Locking: serialized with @throttle() and termios modification by the
 *	tty layer.
 *
 * @send_xchar: ``void ()(struct uart_port *port, char ch)``
 *
 *	Transmit a high priority character, even if the port is stopped. This
 *	is used to implement XON/XOFF flow control and tcflow(). If the serial
 *	driver does not implement this function, the tty core will append the
 *	character to the circular buffer and then call start_tx() / stop_tx()
 *	to flush the data out.
 *
 *	Do not transmit if @ch == '\0' (%__DISABLED_CHAR).
 *
 *	Locking: none.
 *	Interrupts: caller dependent.
 *
 * @start_rx: ``void ()(struct uart_port *port)``
 *
 *	Start receiving characters.
 *
 *	Locking: @port->lock taken.
 *	Interrupts: locally disabled.
 *	This call must not sleep
 *
 * @stop_rx: ``void ()(struct uart_port *port)``
 *
 *	Stop receiving characters; the @port is in the process of being closed.
 *
 *	Locking: @port->lock taken.
 *	Interrupts: locally disabled.
 *	This call must not sleep
 *
 * @enable_ms: ``void ()(struct uart_port *port)``
 *
 *	Enable the modem status interrupts.
 *
 *	This method may be called multiple times. Modem status interrupts
 *	should be disabled when the @shutdown() method is called.
 *
 *	Locking: @port->lock taken.
 *	Interrupts: locally disabled.
 *	This call must not sleep
 *
 * @break_ctl: ``void ()(struct uart_port *port, int ctl)``
 *
 *	Control the transmission of a break signal. If @ctl is nonzero, the
 *	break signal should be transmitted. The signal should be terminated
 *	when another call is made with a zero @ctl.
 *
 *	Locking: caller holds tty_port->mutex
 *
 * @startup: ``int ()(struct uart_port *port)``
 *
 *	Grab any interrupt resources and initialise any low level driver state.
 *	Enable the port for reception. It should not activate RTS nor DTR;
 *	this will be done via a separate call to @set_mctrl().
 *
 *	This method will only be called when the port is initially opened.
 *
 *	Locking: port_sem taken.
 *	Interrupts: globally disabled.
 *
 * @shutdown: ``void ()(struct uart_port *port)``
 *
 *	Disable the @port, disable any break condition that may be in effect,
 *	and free any interrupt resources. It should not disable RTS nor DTR;
 *	this will have already been done via a separate call to @set_mctrl().
 *
 *	Drivers must not access @port->state once this call has completed.
 *
 *	This method will only be called when there are no more users of this
 *	@port.
 *
 *	Locking: port_sem taken.
 *	Interrupts: caller dependent.
 *
 * @flush_buffer: ``void ()(struct uart_port *port)``
 *
 *	Flush any write buffers, reset any DMA state and stop any ongoing DMA
 *	transfers.
 *
 *	This will be called whenever the @port->state->xmit circular buffer is
 *	cleared.
 *
 *	Locking: @port->lock taken.
 *	Interrupts: locally disabled.
 *	This call must not sleep
 *
 * @set_termios: ``void ()(struct uart_port *port, struct ktermios *new,
 *			struct ktermios *old)``
 *
 *	Change the @port parameters, including word length, parity, stop bits.
 *	Update @port->read_status_mask and @port->ignore_status_mask to
 *	indicate the types of events we are interested in receiving. Relevant
 *	ktermios::c_cflag bits are:
 *
 *	- %CSIZE - word size
 *	- %CSTOPB - 2 stop bits
 *	- %PARENB - parity enable
 *	- %PARODD - odd parity (when %PARENB is in force)
 *	- %ADDRB - address bit (changed through uart_port::rs485_config()).
 *	- %CREAD - enable reception of characters (if not set, still receive
 *	  characters from the port, but throw them away).
 *	- %CRTSCTS - if set, enable CTS status change reporting.
 *	- %CLOCAL - if not set, enable modem status change reporting.
 *
 *	Relevant ktermios::c_iflag bits are:
 *
 *	- %INPCK - enable frame and parity error events to be passed to the TTY
 *	  layer.
 *	- %BRKINT / %PARMRK - both of these enable break events to be passed to
 *	  the TTY layer.
 *	- %IGNPAR - ignore parity and framing errors.
 *	- %IGNBRK - ignore break errors. If %IGNPAR is also set, ignore overrun
 *	  errors as well.
 *
 *	The interaction of the ktermios::c_iflag bits is as follows (parity
 *	error given as an example):
 *
 *	============ ======= ======= =========================================
 *	Parity error INPCK   IGNPAR
 *	============ ======= ======= =========================================
 *	n/a	     0	     n/a     character received, marked as %TTY_NORMAL
 *	None	     1	     n/a     character received, marked as %TTY_NORMAL
 *	Yes	     1	     0	     character received, marked as %TTY_PARITY
 *	Yes	     1	     1	     character discarded
 *	============ ======= ======= =========================================
 *
 *	Other flags may be used (eg, xon/xoff characters) if your hardware
 *	supports hardware "soft" flow control.
 *
 *	Locking: caller holds tty_port->mutex
 *	Interrupts: caller dependent.
 *	This call must not sleep
 *
 * @set_ldisc: ``void ()(struct uart_port *port, struct ktermios *termios)``
 *
 *	Notifier for discipline change. See
 *	Documentation/driver-api/tty/tty_ldisc.rst.
 *
 *	Locking: caller holds tty_port->mutex
 *
 * @pm: ``void ()(struct uart_port *port, unsigned int state,
 *		 unsigned int oldstate)``
 *
 *	Perform any power management related activities on the specified @port.
 *	@state indicates the new state (defined by enum uart_pm_state),
 *	@oldstate indicates the previous state.
 *
 *	This function should not be used to grab any resources.
 *
 *	This will be called when the @port is initially opened and finally
 *	closed, except when the @port is also the system console. This will
 *	occur even if %CONFIG_PM is not set.
 *
 *	Locking: none.
 *	Interrupts: caller dependent.
 *
 * @type: ``const char *()(struct uart_port *port)``
 *
 *	Return a pointer to a string constant describing the specified @port,
 *	or return %NULL, in which case the string 'unknown' is substituted.
 *
 *	Locking: none.
 *	Interrupts: caller dependent.
 *
 * @release_port: ``void ()(struct uart_port *port)``
 *
 *	Release any memory and IO region resources currently in use by the
 *	@port.
 *
 *	Locking: none.
 *	Interrupts: caller dependent.
 *
 * @request_port: ``int ()(struct uart_port *port)``
 *
 *	Request any memory and IO region resources required by the port. If any
 *	fail, no resources should be registered when this function returns, and
 *	it should return -%EBUSY on failure.
 *
 *	Locking: none.
 *	Interrupts: caller dependent.
 *
 * @config_port: ``void ()(struct uart_port *port, int type)``
 *
 *	Perform any autoconfiguration steps required for the @port. @type
 *	contains a bit mask of the required configuration. %UART_CONFIG_TYPE
 *	indicates that the port requires detection and identification.
 *	@port->type should be set to the type found, or %PORT_UNKNOWN if no
 *	port was detected.
 *
 *	%UART_CONFIG_IRQ indicates autoconfiguration of the interrupt signal,
 *	which should be probed using standard kernel autoprobing techniques.
 *	This is not necessary on platforms where ports have interrupts
 *	internally hard wired (eg, system on a chip implementations).
 *
 *	Locking: none.
 *	Interrupts: caller dependent.
 *
 * @verify_port: ``int ()(struct uart_port *port,
 *			struct serial_struct *serinfo)``
 *
 *	Verify the new serial port information contained within @serinfo is
 *	suitable for this port type.
 *
 *	Locking: none.
 *	Interrupts: caller dependent.
 *
 * @ioctl: ``int ()(struct uart_port *port, unsigned int cmd,
 *		unsigned long arg)``
 *
 *	Perform any port specific IOCTLs. IOCTL commands must be defined using
 *	the standard numbering system found in <asm/ioctl.h>.
 *
 *	Locking: none.
 *	Interrupts: caller dependent.
 *
 * @poll_init: ``int ()(struct uart_port *port)``
 *
 *	Called by kgdb to perform the minimal hardware initialization needed to
 *	support @poll_put_char() and @poll_get_char(). Unlike @startup(), this
 *	should not request interrupts.
 *
 *	Locking: %tty_mutex and tty_port->mutex taken.
 *	Interrupts: n/a.
 *
 * @poll_put_char: ``void ()(struct uart_port *port, unsigned char ch)``
 *
 *	Called by kgdb to write a single character @ch directly to the serial
 *	@port. It can and should block until there is space in the TX FIFO.
 *
 *	Locking: none.
 *	Interrupts: caller dependent.
 *	This call must not sleep
 *
 * @poll_get_char: ``int ()(struct uart_port *port)``
 *
 *	Called by kgdb to read a single character directly from the serial
 *	port. If data is available, it should be returned; otherwise the
 *	function should return %NO_POLL_CHAR immediately.
 *
 *	Locking: none.
 *	Interrupts: caller dependent.
 *	This call must not sleep
