7f58feae3f test: Fix pointer overrun in dm_test_devm_regmap()
This tests calls regmap_read() which takes a uint pointer as an output
parameter. The test was passing a pointer to a u16 which resulted in an
overflow when the output was written. Fix this by following the
regmap_read() API and passing a uint pointer instead.

2177f924bf test: Avoid random numbers in dm_test_devm_regmap()
There is no good reason to use a sequence from rand() here. We may as well
invent our own sequence.

This should molify Coverity which does not use rand() being used.

1b8897c63e test: fix test/dm/regmap.c
regmap_read() only fills the first two bytes of val. The last two bytes are
random data from the stack. This means the test will fail randomly.

For low endian systems we could simply initialize val to 0 and get correct
results. But tests should not depend on endianness. So let's use a pointer
conversion instead.

41575d8e4c dm: treewide: Rename auto_alloc_size members to be shorter
This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

0ced26a494 test: dm: Add tests for regmap managed API and regmap fields
The tests rely on a dummy driver to allocate and initialize the regmaps
and the regmap fields using the managed API. The first test checks if
the regmap config fields like width, reg_offset_shift, range specifiers,
etc work. The second test checks if regmap fields behave properly (mask
and shift are ok) by peeking into the regmap.

e180c2b129 dm: Rename DM test flags to make them more generic
The test flags used by driver model are currently not available to other
tests. Rather than creating two sets of flags, make these flags generic
by changing the DM_ prefix to UT_ and moving them to the test.h header.

This will allow adding other test flags without confusion.

61b29b8268 dm: core: Require users of devres to include the header
At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.

The test did reads after writes but didn't check the value.
It probably was because the sandbox didn't implement the writeX/readX

df9cf1cc08 test: dm: regmap: Fix the long test delay
At present one of the regmap tests takes 5 seconds to run since it waits
for a timeout. This should be handled using sandbox_timer_add_offset()
which advances time for test purposes.

This requires a little change to make the regmap_read_poll_timeout()
testable.

Update the macro and the test.

82744c20e6 test: regmap: Increase size of syscon0 memory
The upcoming changes to the regmap interface will contain a proper check
for plausibility when reading/writing from/to a register map. To still
have the current tests pass, increase the size of the memory region for
the syscon0 device, since one of the tests reads and writes beyond this
range.

8c1de5e08b regmap: clean up regmap allocation
Putting zero length array at the end of struct is a common technique
to embed arbitrary length of members.  There is no good reason to let
regmap_alloc_count() branch by "if (count <= 1)".

As far as I understood the code, regmap->base is an alias of
regmap->ranges[0].start, but it is not helpful but make the code
just ugly.

Rename regmap_alloc_count() to regmap_alloc() because the _count
suffix seems pointless.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.
