serial: core: constify struct uart_port {name} field

2017-04-08T16:51:57Z

Don't allow modifications of port name. It's serial core's business only. Signed-off-by: Andy Shevchenko Signed-off-by: Greg Kroah-Hartman

tty: serial_core: Add name field to uart_port struct

2017-03-31T14:56:10Z

Introduce a field to store name of uart_port that can be used to easily identify UART port instances on a system that has more than one UART instance. The name is of the form ttyXN(eg. ttyS0, ttyAMA0,..) where N is number that particular UART instance. This field will be useful when printing debug info for a particular port or in register IRQs with unique IRQ name. Port name is populated during uart_add_one_port().

serial: do not accept sysrq characters via serial port

2017-01-12T10:51:24Z

many embedded boards have a disconnected TTL level serial which can generate some garbage that can lead to spurious false sysrq detects. Signed-off-by: John Crispin Signed-off-by: Felix Fietkau Signed-off-by: Greg Kroah-Hartman

linux: drop bitwise everywhere

2016-12-15T22:13:41Z

__bitwise__ used to mean "yes, please enable sparse checks unconditionally", but now that we dropped __CHECK_ENDIAN__ __bitwise is exactly the same. There aren't many users, replace it by __bitwise everywhere. Signed-off-by: Michael S.

ACPI: parse SPCR and enable matching console

2016-09-28T15:46:46Z

'ARM Server Base Boot Requiremets' [1] mentions SPCR (Serial Port Console Redirection Table) [2] as a mandatory ACPI table that specifies the configuration of serial console. Defer initialization of DT earlycon until ACPI/DT decision is made. Parse the ACPI SPCR table, setup earlycon if required, enable specified console. Thanks to Peter Hurley for explaining how this should work.

tty: serial_core: add tty NULL check to uart_tx_stopped

2016-09-15T10:37:09Z

Commit 761ed4a94582 ("tty: serial_core: convert uart_close to use tty_port_close") created a case where a port used for a console does not get shutdown on tty closing. Then a call to uart_tx_stopped() segfaults because the tty is NULL. This could be fixed to restore old behavior, but we also want to allow tty_ports to work without a tty attached. So this change to allow a NULL tty_struct is needed either way.

serial: earlycon: Extend earlycon command line option to support 64-bit addresses

2016-09-02T13:03:35Z

earlycon implementation used "unsigned long" internally, but there are systems (ARM with LPAE) where sizeof(unsigned long) == 4 and uart is mapped beyond 4GiB address range. Switch to resource_size_t internally and replace obsoleted simple_strtoul() with kstrtoull(). Signed-off-by: Alexander Sverdlin Signed-off-by: Greg Kroah-Hartman

earlycon: mark earlycon code as __used iif the caller is built-in

2016-06-25T21:31:04Z

Keep earlycon related symbols only when CONFIG_SERIAL_EARLYCON is enabled and the driver is built-in. This will be helpful to clean up ifdefs surrounding earlycon code in serial drivers. Signed-off-by: Masahiro Yamada Acked-by: Arnd Bergmann Signed-off-by: Greg Kroah-Hartman
