按照man手册的说法,netmos9805的驱动是从netbsd借鉴过来的
看看NetBSD的config文件:
- # XXX 'puc's aren't really bridges, but there's no better place for them here
- puc* at pci? dev ? function ? # PCI "universal" comm. cards
- ...
- # PCI serial interfaces
- com* at puc? port ? # 16x50s on "universal" comm boards
- ...
- # PCI parallel printer interfaces
- lpt* at puc? port ? # || ports on "universal" comm boards
复制代码
设备树上,puc上面应该还有一个com(对应sio?)或者lpt(对应ppi?)层
我以为设备树的构造应该是 ppi->(其他中间层)->puc->pci
