ath11k is the upstream driver for Qualcomm 802.11ax radios, both for the internal AHB and PCI based cards. This commit does however only provide PCI support while AHB will follow but its SoC specific so it will require an OpenWrt target first. It differs a bit from ath10k as it requires stuff like QRTR, MHI and QMI helpers. PCI variant requires qrtr-mhi and mhi-bus which backports do provide, however we are dropping those in a patch as they will conflict with support for the AHB variant as that one requires qrtr-smd which in turn requires RPMSG and GLINK and its not feasable to provide those in backports as they are really SoC specific. QRTR and MHI in kernel 5.10 are not usable and backporting the changes is not easy as they have changed drastically from 5.10 to 5.15 ath11k will only be available on targets that use kernel 5.15.

Subject: [PATCH] backports: drop QRTR and MHI
|
|
|
|
Backports currently include QRTR and MHI due to ath11k-pci requiring them,
|
|
however this at the same time prevents us from adding ath11k-ahb as it
|
|
also requires QRTR however its AHB variant from the kernel will conflict
|
|
with the core provided by backports.
|
|
|
|
Since MHI also conflicts with existing OpenWrt kmods providing MHI drop
|
|
both from backports and use the ones provided by OpenWrt kernel.
