Subject: [PATCH 2/2] wifi: ath11k: add support for QCA2066
Date:   Mon, 7 Aug 2023 14:17:49 +0800

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 does not. To differentiate
them, subversion numbers are used. Currently four numbers are used
by QCA2066: 0x1019A0E1, 0x1019B0E1, 0x1019C0E1 and 0x1019D0E1.

Tested-on: QCA2066 hw2.1 PCI WLAN.HSP.1.1-03737-QCAHSPSWPL_V2_SILICONZ_CE-1
Tested-on: WCN6855 hw2.1 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3
