[clock_time] Fix rt_timespec_to_tick availability for POSIX semaphores

2025-12-28T23:36:08Z

- Moved rt_timespec_to_tick outside of RT_USING_CLOCK_TIME guard - Function now available with just RT_USING_POSIX_CLOCK defined - Fixes undefined reference error when building with POSIX semaphores - Maintains backward compatibility with configurations that don't use clock_time yet Co-authored-by: BernardXiong <1241087+BernardXiong@users.noreply.github.com>

[clock_time] Fix all remaining ktime references in codebase

2025-12-05T15:36:46Z

- Updated dev_soft_rtc.c: RT_USING_KTIME → RT_USING_CLOCK_TIME - Updated vdso_data.c (risc-v): rt_ktime_boottime_get_ns → rt_clock_time_boottime_ns - Updated vdso_data.c (aarch64): rt_ktime_boottime_get_ns → rt_clock_time_boottime_ns - Updated pic.c: rt_ktime_boottime_get_ns → rt_clock_time_boottime_ns - Updated hwtimer-rockchip_timer.c: All rt_ktime_* → rt_clock_* APIs - Renamed base_ktime_ts to base_clocktime_ts in soft_rtc - All ktime API references replaced with clock_time equivalents Co-authored-by: BernardXiong <1241087+BernardXiong@users.noreply.github.com>

[clock_time] Remove compatibility layers and refactor to direct implementation

2025-12-04T17:06:21Z

[clock_time] Remove old subsystems and update to use only clock_time

2025-12-04T15:55:27Z

- Deleted ktime, cputime, and hwtimer directories completely - Removed old header files (ktime.h, cputime.h, cputimer.h, hwtimer.h) - Updated ctime.c to only use RT_USING_CLOCK_TIME (removed RT_USING_KTIME conditionals) - Updated main drivers Kconfig to remove old subsystem entries - Added all legacy API declarations to clock_time.h when compatibility is enabled - Added legacy type definitions (rt_clock_cputime_ops, rt_cputimer) to clock_time.h - Removed ktime.h include from ktime_compat.c (types now in clock_time.h) - All POSIX time APIs (clock_gettime, clock_settime, timer_create, etc.) continue to work Co-authored-by: BernardXiong <1241087+BernardXiong@users.noreply.github.com>
