serial/arc: constify uart_ops structures

2016-09-01T19:05:41+00:00

Check for uart_ops structures that are only stored in the ops field of a
uart_port structure.  This field is declared const, so uart_ops structures
that have this property can be declared as const also.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// 
@r disable optional_qualifier@
identifier i;
position p;
@@
static struct uart_ops i@p = { ... };

@ok@
identifier r.i;
struct uart_port e;
position p;
@@
e.ops = &i@p;

@bad@
position p != {r.p,ok.p};
identifier r.i;
struct uart_ops e;
@@
e@i@p

@depends on !bad disable optional_qualifier@
identifier r.i;
@@
static
+const
 struct uart_ops i = { ... };
//

earlycon: Use common framework for earlycon declarations

2016-02-07T06:07:37+00:00

Use a single common table of struct earlycon_id for both command line
and devicetree. Re-define OF_EARLYCON_DECLARE() macro to instance a
unique earlycon declaration (the declaration is only guaranteed to be
unique within a compilation unit; separate compilation units must still
use unique earlycon names).

The semantics of OF_EARLYCON_DECLARE() is different; it declares an
earlycon which can matched either on the command line or by devicetree.
EARLYCON_DECLARE() is semantically unchanged; it declares an earlycon
which is matched by command line only. Remove redundant instances of
EARLYCON_DECLARE().

This enables all earlycons to properly initialize struct console
with the appropriate name and index, which improves diagnostics and
enables direct earlycon-to-console handoff.

tty: serial: drop owner assignment from platform_drivers

2014-10-20T14:21:45+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.

serial/arc: Fix warning with CONSOLE_POLL

2014-07-12T00:49:46+00:00

| drivers/tty/serial/arc_uart.c:516:2: warning: (near initialization for 'arc_serial_pops.poll_put_char') [enabled by default]

This partially undoes "serial/arc: use uart_console_write() helper" by
restoring the prototpye of poll helper and use a different one in
uart_console_write()
