dm: stdio: Allow lazy probing of video devices

2016-10-11T03:55:33+00:00

At present all video devices are probed on start-up. It would be better to
probe a device only when it is needed. This can happen if it is referenced
in the stdout environment variable, for example.

Add support for this by searching for a suitable device when needed, probing
it, and finding the stdio device it creates.

stdio: Correct a build error with driver model

2016-01-22T03:42:36+00:00

When driver model is used for video but not for the keyboard, a compiler
warnings is produced. Fix it.

dm: stdio: video: Plumb the video uclass into stdio

2016-01-21T02:10:15+00:00

Register video drivers with stdio so that they can be used for text output.
This needs to be done explicitly for now. At some point we should be able to
convert stdio itself to driver model and avoid this step.

dm: stdio: Plumb in the new keyboard uclass

2015-11-20T03:13:40+00:00

When driver model is used for keyboards we must scan the available keyboards
and register them with stdio. Add code to do this.

At some point (once LCD/video is converted) we should be able to convert
stdio to driver model and avoid these dual data structures.

video: Drop DEV_FLAGS_SYSTEM flag

2015-11-05T07:22:21+00:00

DEV_FLAGS_SYSTEM does not have any actual meaning, hence drop it.

stdio: Fix memleak on stdio_deregister

2014-11-04T05:04:00+00:00

stdio_register makes a malloc-ed copy of struct stdio_dev through stdio_clone,
free the malloc-ed memory on stdio_deregister.

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.
