2017-12-07T20:17:00+00:00

This does not appear to be used by any boards. Before introducing a new
log system, remove this old one.

stdio: Correct numbering logic in stdio_probe_device()

2016-11-26T00:59:30+00:00

The current code assumes that the devices are ordered corresponding to
their alias value. But (for example) video1 can come before video0 in the
device tree.

Correct this, by always looking for device 0 first. After that we can fall
back to finding the first available device.

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.

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.

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