regmap: fix kcalloc() arguments order 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: ram: support noinc semantics Support noinc semantics in RAM backed regmaps, for testing purposes. Add a new callback that selects registers which should have noinc behavior. Bulk writes to a noinc register will cause the last value in the buffer to be assigned to the register, while bulk reads will copy the same value repeatedly into the buffer. This patch only adds support to regmap-raw-ram, since regmap-ram does not support bulk operations.
