For WiFi 7 chips, the PCI settings are similar, but registers' names are
changed, so it will be difficult to understand the code if we mix the code
of two generations into one function. Therefore, we add a struct to
abstract PCI generation info, and put the code used by WiFi 7 chips
in pci_be.c.

Then, the struct hierarchy looks like

 rtwdev
   |
   v
 const struct rtw89_pci_info *pci_info;   // per chip (e.g. 8922ae.c)
   |
   v
 const struct rtw89_pci_gen_def *gen_def; // per generation (e.g. pci_be.c)

Ping-Ke Shih (5):
  wifi: rtw89: pci: add PCI generation information to pci_info for each
    chip
  wifi: rtw89: pci: use gen_def pointer to configure mac_{pre,post}_init
    and clear PCI ring index
  wifi: rtw89: pci: implement PCI mac_pre_init for WiFi 7 chips
  wifi: rtw89: pci: add LTR v2 for WiFi 7 chip
  wifi: rtw89: pci: implement PCI mac_post_init for WiFi 7 chips
