Description
计划在v5.1.0中对设备驱动部分做一个全新的调整，主要包括到几个方面：
- 全新的设备驱动模型，设备是可以看得到、可操作的对象（例如可以使用list device可以看到，或者/dev下存在的设备对象（文件））；驱动是针对系列设备的驱动程序，更多突出的是程序的概念。同时也包括，数个设备可能使用同一份驱动；
- rt_device相关代码都从内核中分离，对应的头文件，源文件都从内核中剥离；
- 针对A核平台，全面启用设备树，并推进IP化的驱动方式，基础类型包括：
- pinctl - GPIO及管脚复用；
- clk - 时钟树框架

Research direction
The issue proposes a broad device-driver redesign for v5.1.0, including rt_device separation, device-tree support on A-core platforms, and pinctl and clk foundations. No files, tests, or entry points are named; start by locating rt_device and the existing A-core driver and device-tree code. Done would require the proposed architecture to be implemented and its device and driver behavior validated.
