Subject: [PATCH 0/2] wifi: ath11k: add support for QCA2066

QCA2066 is a PCI based DBS device. It is very similar to WCN6855
overall: they share the same PCI device ID, the same major and
minor version numbers, the same register address, and same HAL
descriptors etc. The most significant difference is that QCA2066
supports 3-antenna configuration while WCN6855 doesn't. To
differentiate them, subversion numbers are used. Currently four
numbers are used by QCA2066: 0x1019A0E1, 0x1019B0E1, 0x1019C0E1
and 0x1019D0E1.

In order to read subversion register, pci.ops needs to be ready
at that time, this change is done in the first patch.

The second patch enables support for QCA2066.

Depends on:
Carl Huang: public review
wifi: ath11k: supports 2 station interfaces

Baochen Qiang (2):
wifi: ath11k: move pci.ops registration ahead
wifi: ath11k: add support for QCA2066

Subject: [PATCH 1/2] wifi: ath11k: move pci.ops registration ahead

In ath11k_pci_probe() there is a switch statement that, based
upon the PCI device ID, assigns pci_ops. After the switch,
ath11k_pcic_register_pci_ops() is called to register the pci_ops.

Unfortunately, this registration is too late if any of the cases
in the switch need to perform operations that require the pci_ops
to already be registered. In particular, an upcoming patch for
QCA2066 needs to call ath11k_pcic_read32().

To address this issue, call ath11k_pcic_register_pci_ops() from
each case instead of doing so after the switch. That way the ops
will be registered if any subsequent operations within the case
processing require the ops to be present.

Tested-on: WCN6855 hw2.1 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3

I'll now drop these from my queue, please resubmit as v2 once we have
pushed the firmware to public.
