Subject: [PATCH 0/5] PCI/VPD: Add and use pci_read/write_vpd_any()
Date: Fri, 10 Sep 2021 08:20:23 +0200	[thread overview]
Message-ID: <ba0b18a3-64d8-d72f-9e9f-ad3e4d7ae3b8@gmail.com> (raw)

In certain cases we need a variant of pci_read_vpd()/pci_write_vpd() that
does not check against dev->vpd.len. Such cases are:
- reading VPD if dev->vpd.len isn't set yet (in pci_vpd_size())
- devices that map non-VPD information to arbitrary places in VPD address
  space (example: Chelsio T3 EEPROM write-protect flag)
Therefore add function variants that check against PCI_VPD_MAX_SIZE only.

Make the cxgb3 driver the first user of the new functions.

Preferably this series should go through the PCI tree.

Heiner Kallweit (5):
  PCI/VPD: Add pci_read/write_vpd_any()
  PCI/VPD: Use pci_read_vpd_any() in pci_vpd_size()
  cxgb3: Remove t3_seeprom_read and use VPD API
  cxgb3: Use VPD API in t3_seeprom_wp()
  cxgb3: Remove seeprom_write and user VPD API
