dm: console: Check for serial devices properly

2017-07-31T16:21:40+00:00

With driver model the serial device is often not called "serial". Mark
driver-model stdio devices so that they can be detected and we can look up
the uclass. This is a more reliable way of finding out whether the console
is connected to a serial device or not.

Convert CONFIG_SYS_STDIO_DEREGISTER to Kconfig

2016-10-23T22:34:17+00:00

This converts the following to Kconfig:
   CONFIG_SYS_STDIO_DEREGISTER

This option should never be enabled in SPL, so use
CONFIG_IS_ENABLED(SYS_STDIO_DEREGISTER) when checking the option.

stdio: extend "name" to 32 symbols

2015-03-06T01:50:29+00:00

With limit of 16 symbols very simple device names derived drom device
tree description could not be displayed correctly.

For example "serial0@0xc0fc1000" will be truncated to sensless
"serial0@0xc0fc10" - note dropped tariling zeros.

stdio: Add force parameter to stdio_deregister

2014-10-06T12:50:43+00:00

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.

dm: Make driver model available before board_init()

2014-09-10T18:59:58+00:00

For some boards board_init() will change GPIOs, so we need to have driver
model available before then. Adjust the board init to arrange this, but
enable it for driver model only, just to be safe.

This does create additional #ifdef logic, but it is safer than trying to
make a pervasive change which may cause some boards to break.

stdio: Provide functions to add/remove devices using stdio_dev

2014-07-23T13:07:24+00:00

The current functions for adding and removing devices require a device name.
This is not convenient for driver model, which wants to store a pointer to
the relevant device. Add new functions which provide this feature and adjust
the old ones to call these.

stdio: Pass device pointer to stdio methods

2014-07-23T13:07:23+00:00

At present stdio device functions do not get any clue as to which stdio
device is being acted on. Some implementations go to great lengths to work
around this, such as defining a whole separate set of functions for each
possible device.

For driver model we need to associate a stdio_dev with a device. It doesn't
seem possible to continue with this work-around approach.

Instead, add a stdio_dev pointer to each of the stdio member functions.

Note: The serial drivers have the same problem, but it is not strictly
necessary to fix that to get driver model running. Also, if we convert
serial over to driver model the problem will go away.

Code size increases by 244 bytes for Thumb2 and 428 for PowerPC.

serial: arm_dcc: Remove stdio structure support

Removed stdio structure ops support on arm_dcc
driver, and need to register with serial core
so-that it can access like remianing serial drivers.
