regmap: kunit: Create a struct device for the regmap2024-04-08T15:38:07+00:00Richard Fitzgeraldrf@opensource.cirrus.com2024-04-08T14:45:51+00:00urn:sha1:7b7982f14315e0f6910e13b22ed38a47144a83ec
Use kunit_device_register() to create a real struct device for the
regmap instead of leaving it at NULL.
The main reason for this is that it allows context data to be passed
into the readable_reg/writable_reg/volatile_reg functions by attaching
it to the struct device with dev_set_drvdata().
The gen_regmap() and gen_raw_regmap() functions are updated to take a
struct kunit * argument.
A new struct regmap_test_priv has been created to hold the struct device
created by kunit_device_register(). This allows the struct to be
extended in the future to hold more private data for the test suite.

regmap: fix kcalloc() arguments order2023-12-20T18:11:38+00:00Dmitry Antipovdmantipov@yandex.ru2023-12-20T17:58:19+00:00urn:sha1:3b201c9af7c0cad2e8311d96c0c1b399606c70fa
When compiling with gcc version 14.0.0 20231220 (experimental)
and W=1, I've noticed a bunch of four similar warnings like:
drivers/base/regmap/regmap-ram.c: In function '__regmap_init_ram':
drivers/base/regmap/regmap-ram.c:68:37: warning: 'kcalloc' sizes specified with
'sizeof' in the earlier argument and not in the later argument [-Wcalloc-transposed-args]
68 | data->read = kcalloc(sizeof(bool), config->max_register + 1,
| ^~~~
Since 'n' and 'size' arguments of 'kcalloc()' are multiplied to
calculate the final size, their actual order doesn't affect the
result and so this is not a bug. But it's still worth to fix it.

regmap: Add RAM backed register map2023-03-30T11:25:42+00:00Mark Brownbroonie@kernel.org2023-03-26T14:11:12+00:00urn:sha1:f6352424e37e7bf72291ceab87dc620172be0999
Add a register map that is a simple array of memory, for use in
KUnit testing of the framework. This is not exposed in regmap.h
since I can't think of a non-test use case, it is purely for use
internally. To facilitate testing we track if registers have been
read or written to.
