serial: 8250: Name MSR literals

2023-01-19T14:01:19+00:00

Add UART_MSR_STATUS_BITS for CD, RI, DSR & CTS. Use names for the
literal.

Don't make the define for combined flags part of UAPI.

serial: 8250: Use defined IER bits

2023-01-19T14:01:19+00:00

Instead of literal 0x0f, add a define for enabling all IER bits the
8250 driver is interested in.

Don't make the define for combined flags part of UAPI.

serial: Consolidate BOTH_EMPTY use

2022-06-27T12:41:31+00:00

Per file BOTH_EMPTY defines are littering our source code here and
there. Define once in serial.h and create helper for the check
too.

serial: Convert SERIAL_XMIT_SIZE to UART_XMIT_SIZE

2022-06-27T12:41:31+00:00

Both UART_XMIT_SIZE and SERIAL_XMIT_SIZE are defined. Make them all
UART_XMIT_SIZE.

tty: serial: define UART_LCR_WLEN() macro

2022-02-28T20:49:06+00:00

Define a generic UART_LCR_WLEN() macro with a size argument. It can be
used to encode byte size into an LCR value. Therefore we can use it to
simplify the drivers using tty_get_char_size() in the next patches.

serial: diminish usage of struct serial_uart_config

2012-09-05T20:15:07+00:00

This structure might have made sense many years ago, but at this
point it is only used in one specific driver, and referenced in
stale comments elsewhere.  Rather than change the sunsu.c driver,
simply move the struct to be within the exclusive domain of that
driver, so it won't get inadvertently picked up and used by other
serial drivers going forward.  The comments referencing the now
driver specific struct are updated accordingly.

Note that 8250.c has a struct that is similar in usage, with the
name serial8250_config; but is 100% independent and untouched here.

tty: move the async flags from the serial code into the tty includes

2012-09-05T20:11:03+00:00

These are used with the tty_port flags which are tty generic so move the
flags into a more sensible place. This then makes it possible to add
helpers such as those suggested by Huang Shijie.

serial: delete the MCA specific 8250 support.

2012-05-17T23:02:14+00:00

The support for CONFIG_MCA is being removed, since the 20
year old hardware simply isn't capable of meeting today's
software demands on CPU and memory resources.

This commit removes the MCA specific 8250 UART code.

TTY: serial, simplify ASYNC_USR_MASK

By using ASYNC_SPD_MASK instead of the single speed bits.
