I don't think these meet the spirit of the guidance in pci_ids.h, which is there to minimize churn in that file and make backports easier: * Do not add new entries to this file unless the definitions * are shared between multiple drivers. PCI_DEVICE_ID_NXP2_NETC_TIMER and PCI_DEVICE_ID_NXP2_ENETC_VF aren't used at all by this series, so they shouldn't be added to pci_ids.h. PCI_DEVICE_ID_NXP2_NETC_EMDIO is used only by drivers/net/ethernet/freescale/enetc/enetc_pci_mdio.c, so it should be defined there, not in pci_ids.h. PCI_DEVICE_ID_NXP2_ENETC_PF is used by enetc.c and enetc4_pf.c, but it looks like those are basically part of the same driver, and it could be defined in enetc4_hw.h or similar. > --- > v5: no changes > --- > include/linux/pci_ids.h | 7 +++++++ > 1 file changed, 7 insertions(+) > > diff --git a/include/linux/pci_ids.h b/include/linux/pci_ids.h > index 4cf6aaed5f35..acd7ae774913 100644 > --- a/include/linux/pci_ids.h > +++ b/include/linux/pci_ids.h > @@ -1556,6 +1556,13 @@ > #define PCI_DEVICE_ID_PHILIPS_SAA7146 0x7146 > #define PCI_DEVICE_ID_PHILIPS_SAA9730 0x9730 > > +/* NXP has two vendor IDs, the other one is 0x1957 */ > +#define PCI_VENDOR_ID_NXP2 PCI_VENDOR_ID_PHILIPS > +#define PCI_DEVICE_ID_NXP2_ENETC_PF 0xe101 > +#define PCI_DEVICE_ID_NXP2_NETC_EMDIO 0xee00 > +#define PCI_DEVICE_ID_NXP2_NETC_TIMER 0xee02 > +#define PCI_DEVICE_ID_NXP2_ENETC_VF 0xef00 > + > #define PCI_VENDOR_ID_EICON 0x1133 > #define PCI_DEVICE_ID_EICON_DIVA20 0xe002 > #define PCI_DEVICE_ID_EICON_DIVA20_U 0xe004 > -- > 2.34.1 >
