feat(dm): support OFW on Cortex-M targets

2026-08-12T04:54:50Z

Add the ARM NVIC PIC driver, no-MMU I/O mapping, built-in FDT support, and Cortex-M CPU hooks required by the native RT-Thread device model.

[dm][core] Add rt_bus_probe_device API

2026-08-03T01:36:21Z

Add rt_bus_probe_device() to retry driver matching for a registered but unbound device. Use it when an OFW-created platform device is requested again, while preserving native-bus ownership for I2C, SPI, and other non-platform devices. Also instantiate eligible child platform devices after a parent node is registered. Signed-off-by: GuEe-GUI <2991707448@qq.com>

[drivers] Fix OFW bus conflict and prevent duplicate device creation

2026-01-20T14:05:28Z

Problem: When enumerating device tree nodes, platform bus and native buses (I2C/SPI) may create duplicate devices for the same OFW node, causing cross-bus conflicts. This triggers assertion failure '(dev->bus != new_bus)' in rt_bus_reload_driver_device() during boot on minimal DM-enabled systems. Root Cause: 1. Platform bus tries to reload devices that already belong to other buses by calling rt_bus_reload_driver_device(dev->bus, dev), which violates the API contract (requires dev->bus != new_bus). 2. Native buses (I2C/SPI) do not mark OFW nodes as occupied, so platform bus creates duplicate platform devices for I2C/SPI client nodes. Solution: 1. components/drivers/core/platform_ofw.c: Return RT_EOK when np->dev exists, letting the native bus handle device lifecycle instead of cross-bus reload. 2. components/drivers/i2c/dev_i2c_bus.c: Mark i2c_client_np->dev during scan to prevent platform bus from duplicating I2C client devices. 3. components/drivers/spi/dev_spi_bus.c: Mark spi_dev_np->dev during scan to prevent platform bus from duplicating SPI devices. Tested on Spacemit K1 RISC-V platform with minimal DM configuration. Signed-off-by: lhxj <2743257167@qq.com>
