19693: sys/color: extend unittest and fix module r=maribu a=kfessel
### Contribution description
this extends the unittest for sys_color testing more colors
### Testing procedure
```
RIOT_tree/tests/unittests$ make tests-color test
```
will fail since our `rgb2hsv` implementation is wrong (or is using an other colorspace than hsv2rgb (without documenting))
the new `hsv2rgb` test will succeed
### Issues/PRs references
#19614 was the reason i had a look at this
#1315 added the rgb2hsv and hsv2rgb function
#9940 added the test for black special case
https://www.vagrearg.org/content/hsvrgb << some optimization for that function (avoiding float)

19601: SUIT: Prepared manifests r=chrysn a=chrysn
### Contribution description
While SUIT can generally be used already with manifests that are "dropped into memory" (by any mechanism), the convenient SUIT worker thread mechanism so far could not be used with it.
This adds the suit_worker_try_prepare / suit_worker_trigger_prepared
pair for using the SUIT worker, and breaks suit_handle_manifest_buf out
of suit_handle_url (where the latter now calls the former).
#### By-catch
As part of factoring out reaping of the zombie worker thread, a locking
error that deadlocks the SUIT worker in case the race between the mutex
being unlocked and the thread being reaped hits the necessary handling
code is fixed (and mutex_unlock is called in the error path).
### Testing procedure
SUIT tests should pass.
https://github.com/RIOT-OS/RIOT/pull/19659 provides a demo of how the new API is used.
### Issues/PRs references
I think that the currently employed mechanism of having a resource to which a URL with the manifest gets posted is contrary to the design goals of SUIT -- the signed manifest should be what justifies the device to spend resources (eg. get data from a server), not a URI that is just *not* signed.
This PR makes it easier to implement a resource to which the manifest can be POSTed, rather than a CoAP URI that represents the manifest, as is proposed (but not mature) in
https://github.com/RIOT-OS/RIOT/pull/19659.

19618: cpu/stm32: fix riotboot settings for L4 and WB r=benpicco a=gschorcht
### Contribution description
This PR fixes the `riotboot` configuration for L4 and WB.
The family is not called `stm32l4` or `stm32wb` but `l4` and `wb`. That is, the `riotboot` configuration didn't work at all. Furthermore, a minimum `RIOTBOOT_LEN` of `0x2000` is required for L4.
Found when investigating the compilation errors for `bootloaders/riotboot_serial` in PR #19576.
### Testing procedure
1. Green CI.
2. Use the following commands:
```
BOARD=nucleo-l496zg make -C tests/riotboot info-debug-variable-RIOTBOOT_HDR_LEN
BOARD=p-nucleo-wb55 make -C tests/riotboot info-debug-variable-RIOTBOOT_HDR_LEN
```
In master these commands give
```
0x400
```
With this PR these commands give
```
0x200
```
as expected.
3. Use the following commands:
```
BOARD=nucleo-l496zg make -C tests/riotboot info-debug-variable-RIOTBOOT_LEN
BOARD=p-nucleo-wb55 make -C tests/riotboot info-debug-variable-RIOTBOOT_LEN
```
In master these commands give
```
0x1000
```
With this PR these commands give
```
0x2000
```
as expected.

19581: cpu/samd5x: enable FDPLL1 at 200MHz r=benpicco a=dylad
### Contribution description
This PR allows to use the second FDPLL (the first one is used to generated the 120MHz frequency used by the core and some peripherals). The second FDPLL is setup to run at 200MHz which is the maximum allowed by this MCU.
In fact, I reused the existing function which setup FDPLL0 so it can be used in a generic way for both PLL (since they are the same IP).
I change the way the computation offset (left shift by 5) is done because 200MHz << 5 wouldn't fit inside an `uint32_t` and I wanted to avoid using an `uint64_t` here
Two additional commits are present for a small cleanup and a fix.
This is currently unused in our codebase, so it shouldn't impact this platform too much as the `ONDEMAND` bit is set. the FDPLL will not be running out of the box. But `@gschorcht` might need it pretty soon.
### Testing procedure
This PR can be tested on a `same54-xpro` and an oscilloscope using the following the patch:

### Contribution description
No architecture makes use of thread_arch_t anymore, so let's drop it.
Co-authored-by: Marian Buschsieweke <marian.buschsieweke@ovgu.de>
Rather than setting the correct blk_len, the code only wrote 1 and 0
into the three bytes due to the use of a logic and where a bitwise
and should be used.
The coreclk shell command now prints the CPU frequency in Hz, which
can be useful for boards with RC generated CPU frequency (e.g.
RP2040, FE310, or MPS430Fx1xx MCUs allow this) which may quite a bit
off the target frequency.

19529: cpu/stm32/periph/dac: optimize setting DAC r=benpicco a=Enoch247
### Contribution description
The current implmentation right shifted the 16 bit value passed into `dac_set()` down to the 12 bits that the DAC is actually capable of. This patch drops the shift and instead writes the 16 bit value to the DAC's left aligned 12 bit wide data holding register.
### Testing procedure
do something like:
``` c
#include "perip/dac.h"
int main(void)
{
dac_set(DAC_LINE(0), 0xffff/2);
return 0;
}
```
- observe DAC's output is half of vref

19527: drivers/sdcard_spi: small cleanup r=benpicco a=gschorcht
### Contribution description
This PR provides a small cleanup:
- the copy of `sdcard_spi_params_t` is removed (commit bfc2a51f70)
- the documentation was changed to fit the 100 characters per line. (commit 36f0162b34)
It is not necessary to hold a complete copy `sdcard_spi_params_t` in the device descriptor. Constant parameters can be used directly from ROM instead. This saves 24 bytes of RAM.
### Testing procedure
Use any board with SD Card SPI interface. The driver test should still work, for example:
```
BOARD=esp32-wrover-kit make -j8 -C tests/driver_sdcard_spi flash term
```
```

18620: core: add core_mutex_debug to aid debugging deadlocks r=maribu a=maribu
### Contribution description
Adding `USEMODULE += core_mutex_debug` to your `Makefile` results in
on log messages such as
[mutex] waiting for thread 1 (pc = 0x800024d)
being added whenever `mutex_lock()` blocks. This makes tracing down
deadlocks easier.
### Testing procedure
Run e.g.
```sh
USEMODULE=core_mutex_debug BOARD=nucleo-f767zi make -C tests/mutex_cancel flash test
```
which should provide output such as
```
Welcome to pyterm!

19504: cpu/cc26xx_cc13xx: Fix bogus array-bound warning r=maribu a=maribu
### Contribution description
GCC 12 create a bogus array out of bounds warning as it assumes that because there is special handling for `uart == 0` and `uart == 1`, `uart` can indeed be `1`. There is an `assert(uart < UART_NUMOF)` above that would blow up prior to any out of bounds access.
In any case, optimizing out the special handling of `uart == 1` for when `UART_NUMOF == 1` likely improves the generated code and fixes the warning.

The actual change is a pretty obvious one-liner, so that code review and a green CI should be sufficient. If not, running any UART example app without regression should do.

19506: tools/openocd: Fix handling of OPENOCD_CMD_RESET_HALT r=maribu a=maribu
### Contribution description
The OPENOCD_CMD_RESET_HALT was not longer correctly passed to the script. This fixes the issue.
### Testing procedure

### Issues/PRs references
The change was added to https://github.com/RIOT-OS/RIOT/pull/19050 after testing the PR and before merging. I'm not sure if the fix never worked because of this, or if behavior of `target-export-variables` or GNU Make changed.
