2020-01-06serdev: Don't claim unsupported ACPI serial devicesPunit Agrawal
Serdev sub-system claims all ACPI serial devices that are not already initialised. As a result, no device node is created for serial ports on certain boards such as the Apollo Lake based UP2. This has the unintended consequence of not being able to raise the login prompt via serial connection. Introduce a blacklist to reject ACPI serial devices that should not be claimed by serdev sub-system. Add the peripheral ids for Intel HS UART to the blacklist to bring back serial port on SoCs carrying them.

2019-12-30tty: always relink the portSudip Mukherjee
If the serial device is disconnected and reconnected, it re-enumerates properly but does not link it. fwiw, linking means just saving the port index, so allow it always as there is no harm in saving the same value again even if it tries to relink with the same port.

2019-12-19tty: serial: 21285: stop using the unused[] variable from struct uart_portGreg Kroah-Hartman
Much like the samsung_tty driver (now I know where they copied the idea from), the 21285 uart driver uses 2 bytes from the "unused" array of struct uart_port to keep tx/rx enabled/disabled state. Those fields are going away (they were never really needed in the first place), so fix up the 21285 driver by another horrible hack. Instead of creating a whole structure for just 2 bytes, just use two bits from the private_data pointer instead, as that pointer is never used. The two bits reflect if tx/rx is now enabled/disabled. Astute readers will note that once rx is disabled, nothing ever seems to turn it back on, making one wonder if anyone has ever done this.

2019-12-18tty/serial: Migrate meson_uart to use has_sysrqDmitry Safonov
The SUPPORT_SYSRQ ifdeffery is not nice as: - May create misunderstanding about sizeof(struct uart_port) between different objects - Prevents moving functions from serial_core.h - Reduces readability (well, it's ifdeffery - it's hard to follow) In order to remove SUPPORT_SYSRQ, has_sysrq variable has been added. Initialise it in driver's probe and remove ifdeffery.
