This change fixes intermittent failures of the `core.smp_bind_affinity`
utest across SMP CI targets. The original failure was a flaky assertion on
unbound threads (`thread_inc[x] != thread_tic[x]` in thread_entry), not
incorrect bind_cpu behavior. CI logs already showed T0 binding worked
(thread_inc[0] == thread_tic[0] == 100) while the not_equal check failed.
The root issue is that unbound-thread CPU placement is platform-dependent
and outside the bind_cpu contract. On dual-core RISC-V/ARMv7 CI, an
unbound thread may legitimately run all iterations on core 0 while T0
delays on the same core, so any assertion requiring cross-core migration
(thread_inc != thread_tic, or core_mask with multiple bits) remains flaky.
This patch narrows the test to what bind_affinity actually verifies: T0
bound to core 0 must always execute on core 0. Unbound threads only add
scheduling pressure; their core_mask is printed for observation but not
asserted.
Changes:
- Sample `rt_hw_cpu_id()` and update counters under `rt_sched_lock` to
avoid migration skew between counting and CPU sampling.
- Track `thread_core_mask` for diagnostics; assert only T0 binding via
`thread_inc[0] == thread_tic[0]` and `thread_core_mask[0] == 1`.
- Remove flaky unbound-thread assertions (`thread_inc != thread_tic` and
multi-core core_mask checks).
- Move T0 assertions to the main test thread after all workers finish.
- Use atomic `finsh_flag`; reset counters and `threads[]` in `utest_tc_init`.
- Spin in worker loops after `run_num` until cleanup deletes them (do not
return from thread_entry or use `RT_WAITING_FOREVER` with `rt_thread_delay`).
- Guard `rt_thread_delete` in cleanup with non-NULL checks.

The previous commit placed the test in a new top-level tests/ directory
that does not exist in the RT-Thread repo structure and used the external
check library. Move the test to examples/utest/testcases/lwp/ and rewrite
it using RT-Thread's native utest framework, add a Kconfig symbol
(RT_UTEST_LWP_TTY_PTMX), and wire it into Kconfig.utestcases.

centralize hard I2C per-message route state for DMA, interrupt, and polling paths
make multi-message and no-stop transfers use sequential HAL APIs only
snapshot scheduler and interrupt context once for stable async transfer decisions
reuse the transaction timeout for async wait logging and abort recovery
|
|
snapshot scheduler and interrupt state once per SPI message
reuse the message-level async route decision for all split chunks
disable DMA and interrupt paths consistently when async transfer is unavailable
avoid mixed async and polling policies within one logical SPI transfer

Add Doxygen pages for RT-Thread device-model drivers: platform/OFW,
DM core (bus, dm, power), clk/regulator/reset/power-domain, PCI/PIC,
Phye, DMA/hwcache, block/SCSI/ATA/NVMe/UFS/SDIO, SCMI, RPMsg,
mailbox, NVMem, NUMA, syscon, thermal, input/LED/IIO/graphic, and
related power/charger/supply docs.
Expand device-driver INDEX.md with ~90 @subpage entries so all new
pages appear in the driver chapter navigation.
Update existing UART/SPI/RTC/pin/framework/dtc pages: UART docs moved
from serial/ to uart/ (uart + uart_dm + uart_earlycon); SPI and RTC
gain DM companion pages; pin links to pin_dm; framework points at DM
topics.
Focus on registration/probe flow and in-tree APIs; no standalone
VirtIO subsystem page (transport code still incomplete).
Test plan: build Doxygen for documentation/ and verify device-driver
INDEX links resolve without missing @ref/@subpage warnings.
