SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

dm: core: Add a function to look up a uclass by name

2018-02-03T17:08:40+00:00

Each uclass has a driver name which we can use to look up the uclass. This
is useful for logging, where the uclass ID is used as the category.

Add a function to handle this, as well as a test.

dm: core: Add uclass_first/next_device_check()

2017-07-11T16:08:19+00:00

Sometimes it is useful to iterate through all devices in a uclass and
skip over those which do not work correctly (e.g fail to probe). Add two
new functions to provide this feature.

The caller must check the return value each time to make sure that the
device is valid. But the device pointer is always returned.

These are not as clear as they could be. Tidy them up a bit. Also fix a
tiny code-style nit.

It is useful in debug() statements to display the name of the uclass for a

dm: core: Add a way to find a device by its driver

2016-07-26T02:46:43+00:00

Some SoCs have a single clock device. Provide a way to find it given its
driver name. This is handled by the linker so will fail if the name is not
found, avoiding strange errors when names change and do not match. It is
also faster than a string comparison.
