serial: 8250: export get_mctrl function

2016-04-30T16:26:55+00:00

Exposes get_mctrl() function so that it can be overriden with platform specific implementation. Signed-off-by: Wan Ahmad Zainie Reviewed-by: Andy Shevchenko Reviewed-by: Heikki Krogerus Signed-off-by: Greg Kroah-Hartman

tty: Add software emulated RS485 support for 8250

2016-02-07T06:23:26+00:00

Implementation of software emulation of RS485 direction handling is based on omap_serial driver. Before and after transmission RTS is set to the appropriate value. Note that before calling serial8250_em485_init() the caller has to ensure that UART will interrupt when shift register empty. Otherwise, emultaion cannot be used. Both serial8250_em485_init() and serial8250_em485_destroy() are idempotent functions. Signed-off-by: Matwey V. Kornilov Signed-off-by: Greg Kroah-Hartman

tty/early: make serial8250_early_{in,out} static again

2015-07-24T00:43:30+00:00

Commit ed71871bed719 ("tty/8250_early: Turn serial_in/serial_out into weak symbols") made these routines weak to allow platform specific Big endian override However recent updates to core, specifically ebc5e20082 ("serial: of_serial: Support big-endian register accesses") and 6e63be3fee14 ("serial: earlycon: Add support for big-endian MMIO accesses") means that round about way to overide the early serial accessors is no longer needed.

serial: 8250: Split base port operations from universal driver

2015-07-24T00:43:01+00:00

Refactor base port operations into new file; 8250_port.c. Legacy irq handling, RSA port support, port storage for universal driver, driver definition, module parameters and linkage remain in 8250_core.c The source file split and resulting modules is diagrammed below: 8250_core.c ====> 8250_core.c __ \ \ \ +-- 8250.ko (alias 8250_core) \ 8250_pnp.c __/ (universal driver) \ => 8250_port.c __ \ +-- 8250_base.ko 8250_dma.c __/ (port operations) Signed-off-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman

serial: 8250: Decouple RSA probe

2015-03-26T17:18:20+00:00

Prepare for 8250 split; separate RSA probe and resource management from base port operations. Override base port operations for the config_port(), request_port() and release_port() methods to implement the optional RSA probe and resource management only in the universal/legacy 8250 driver. Introduce 'probe' flags for 8250 ports, which allows drivers higher up the driver stack to enable optional probes. Signed-off-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman

serial: 8250: Separate legacy irq handling from core port operations

2015-03-26T17:15:16+00:00

Prepare for 8250 split; decouple irq setup/teardown and handler from core port operations. Introduce setup_irq() and release_irq() 8250 driver methods; the 8250 core will use these methods to install and remove irq handling for the given 8250 port. Refactor irq chain linking/unlinking from 8250 core into univ8250_setup_irq()/univ8250_release_irq() for the universal 8250 driver. Signed-off-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman

serial: 8250_early: Remove setup_early_serial8250_console()

setup_earlycon() will now match and register the desired earlycon from the param string (as if 'earlycon=...' had been set on the command line). Use setup_earlycon() from existing arch call sites which start an earlycon directly. Acked-by: Rob Herring Signed-off-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman

console: Add extensible console matching

2015-03-26T15:16:20+00:00

Add match() method to struct console which allows the console to perform console command line matching instead of (or in addition to) default console matching (ie., by fixed name and index). The match() method returns 0 to indicate a successful match; normal console matching occurs if no match() method is defined or the match() method returns non-zero. The match() method is expected to set the console index if required. Re-implement earlycon-to-console-handoff with direct matching of "console=uart|uart8250,..." to the 8250 ttyS console.
