[docs] device-driver: add DM subsystem docs and expand INDEX

2026-05-28T08:09:55Z

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. Signed-off-by: GuEe-GUI <2991707448@qq.com>

[components][clock_time] Refactor time subsystem around clock_time (#11111)

2026-01-31T09:44:27Z

* [components][clock_time] Refactor time subsystem around clock_time Introduce the clock_time core with clock source/event separation, high-resolution scheduling, and boot-time helpers, plus clock_timer adapters for timer peripherals. Remove legacy ktime/cputime/hwtimer implementations and migrate arch and BSP time paths to the new subsystem while keeping POSIX time integration functional. Update drivers, Kconfig/SConscript wiring, documentation, and tests; add clock_time overview docs and align naming to clock_boottime/clock_hrtimer/clock_timer. * [components][clock_time] Use BSP-provided clock timer frequency on riscv64 * [risc-v] Use runtime clock timer frequency for tick and delays * [bsp] Add clock timer frequency hooks for riscv64 boards * [bsp] Update Renesas RA driver doc clock_timer link * [bsp] Sync zynqmp-r5-axu4ev rtconfig after config refresh * [bsp][rk3500] Update rk3500 clock configuration * [bsp][hpmicro] Add rt_hw_us_delay hook and update board delays * [bsp][stm32l496-st-nucleo] enable clock_time for hwtimer sample in ci * [bsp][hpmicro] Fix rtconfig include scope for hpm6750evk Move rtconfig.h include outside the ENET_MULTIPLE_PORT guard for hpm6750evk and hpm6750evk2 so configuration macros are available regardless of ENET settings. * [bsp][raspi3] select clock time for systimer * [bsp][hpm5300evk] Trim trailing blank line * [bsp][hpm5301evklite] Trim trailing blank line * [bsp][hpm5e00evk] Trim trailing blank line * [bsp][hpm6200evk] Trim trailing blank line * [bsp][hpm6300evk] Trim trailing blank line * [bsp][hpm6750evk] Trim trailing blank line * [bsp][hpm6750evk2] Trim trailing blank line * [bsp][hpm6750evkmini] Trim trailing blank line * [bsp][hpm6800evk] Trim trailing blank line * [bsp][hpm6e00evk] Trim trailing blank line * [bsp][nxp] switch lpc178x to gcc and remove mcx timer source * [bsp][stm32] fix the CONFIG_RT_USING_CLOCK_TIME issue. * [docs][clock_time] add clock time documentation * [docs][clock_time] Update clock time subsystem documentation - Update device driver index to use correct page reference - Clarify upper layer responsibilities in architecture overview - Update README to describe POSIX/libc, Soft RTC, and device driver usage - Refine architecture diagram with improved layout and color scheme - Remove obsolete clock_timer.md file * [kernel][utest] Trim trailing space * [clock_time] Fix hrtimer wrap handling * [clock_time] fix the static rt_inline issue * [clock_time] fix the rt_clock_hrtimer_control result issue

doxygen: fix two issues when building with doxygen 1.9.8 (#10768)

2025-10-10T02:05:06Z

* doxygen: remove @return command if function return void When doxygen is upgraded to v1.9.8 (on ubuntu 24.04), doxygen reports: "doxygen error: found documented return type for xxx that does not return anything" for those functions which return void but declare "@return" in doxygen comment. Solution: remove "@return" for those cases, and update guide document for how to write doxgen comment for functions.

doxygen: move device_driver under to components for pages

2025-05-29T05:47:46Z

In line with the layout of the source code, the Device-Driver submodule should belong to components. The doxygen Module part has been adjusted. This commit modifies the markdown document part and moves the device-driver pages under to components. Signed-off-by: Chen Wang
