2014-10-24dm: serial: consolidate common code moreMasahiro Yamada
Commit b8893327e9d2 (dm: serial: Put common code into separate functions) consolidated getc() and putc(). This commit does more puts() and tsts(). Also rename locally used functions to _serial_*() for clarification because we have similar functions names here are there in this file.

2014-10-24dm: serial: remove unnecessary castingMasahiro Yamada
The type (void *) can be directly passed to a function that takes a specific pointer type. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Simon Glass <sjg@chromium.org>
2014-10-24dm: serial: fix console putcMasahiro Yamada
Commit b8893327e9d2 (dm: serial: Put common code into separate functions) consolidated getc() correctly, but introduced another bug to putc(); serial_stub_putc() passes sdev->priv to serial_putc_dev(), but serial_putc_dev() uses cur_dev instead of the given argument.

2014-10-24dm: serial: Support CONFIG_CONS_INDEX if availableSimon Glass
Try to use this option to select the correct uart for the console. This mimics the behaviour of drivers/serial.c. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
2014-10-24dm: serial: Reset the watchdog while waiting in getc()Simon Glass
We have moved the busy-wait loop out of drivers and into the uclass. This means that we must reset the watchdog when busy-waiting. Note: some drivers may still have a busy-wait even with driver model, as a transition mechanism. Driver model will tolerate this, and is can be cleaned up when all users of the driver use driver model. An example is ns16550.

2014-10-22dm: serial: Put common code into separate functionsSimon Glass
Avoid duplicating the code which deals with getc() and putc(). It is fairly simple, but may expand later. Signed-off-by: Simon Glass <sjg@chromium.org>

2014-10-06stdio: Add force parameter to stdio_deregisterHans de Goede
In some cases we really want to move forward with a deregister, add a force parameter to allow this, and replace the dev with a nulldev in this case. Signed-off-by: Hans de Goede <hdegoede@redhat.com>

Allow serial_find_console_or_panic() to work without a device tree. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-09-10dm: Add a uclass for serial devicesSimon Glass
Serial devices support simple byte input/output and a few operations to find out whether data is available. Add a basic uclass for serial devices to be used by drivers that are converted to driver model. Signed-off-by: Simon Glass <sjg@chromium.org>
