11 - Jeff Johnson <jjohnson@kernel.org>
14 Qualcomm Technologies IEEE 802.11be PCIe devices with WSI interface.
16 The ath12k devices (QCN9274) feature WSI support. WSI stands for
19 This WSI connection is essential to exchange control information
22 The WSI interface includes TX and RX ports, which are used to connect
23 multiple WSI-supported devices together, forming a WSI group.

71 The WSI controller device in the WSI group aids (is capable) to
73 all devices in the WSI group.
81 This is the TX port of WSI interface. It is attached to the RX
82 port of the next device in the WSI connection.
87 This is the RX port of WSI interface. It is attached to the TX
88 port of the previous device in the WSI connection.
