Hi Jiaxun, I think it is better to define the device IDs in pci_ids.h, otherwise it seems a little disorganized. Thanks, Tiezhu Yang > >> + > > #endif /* _LINUX_PCI_IDS_H */ > > -- > > 2.1.0 > > > >

Please read the comment at the start of this file. New entries should be added only if they're shared by multiple drivers. That's the rule. And probably you can split these two patches into a new series as they're likely to be accepted.

OK, that makes sense. Let me split the two patches 1/6 and 2/6 into a new series, the first patch only adds the Loongson vendor ID to pci_ids.h.

Add the Loongson vendor ID and 7A1000 device IDs to pci_ids.h to be used by the controller driver in the future.
