Devicetree动态解析器说明
========================
本文描述了内核内DeviceTree解析器的实现,它位于drivers/of/resolver.c中。
解析器如何工作?
----------------
解析器被赋予一个任意的树作为输入,该树用适当的dtc选项编译,并有一个/plugin/标签。这就产
生了适当的__fixups__和__local_fixups__节点。
解析器依次通过以下步骤工作:
1. 从实时树中获取最大的设备树phandle值 + 1.
2. 调整树的所有本地 phandles,以解决这个量。
3. 使用 __local__fixups__ 节点信息以相同的量调整所有本地引用。
4. 对于__fixups__节点中的每个属性,找到它在实时树中引用的节点。这是用来标记该节点的标签。
5. 检索fixup的目标的phandle。
6. 对于属性中的每个fixup,找到节点:属性:偏移的位置,并用phandle值替换它。

Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
